Solid Phase Extraction And The Orange Bavarian Cream Connection

Doughnuts probably come into mind from the first mention of Bavarian cream. Try to go to doughnut stores (such as Krispy Kreme, Dunkin’ Donuts, Tim Horton’s) and purchase one of each kind of their custard cream-filled doughnuts (i.e. Boston cream, Long Johns, etc.) including the Bavarian cream. Chances are you will conclude that the members of this doughnut family only vary according to the type of exterior frosting because their fillings have the identical decadently sweet taste and oozingly creamy texture to the confectionary sugar-dusted Bavarian cream doughnut. So what is a Bavarian cream then?

Bavarois or Bavarian cream in English is a cold unmolded custard cream or crème anglaise that has been thickened with cornstarch and gelatin. Unfortunately, the term has become a misnomer and thus, is misused nowadays in the American kitchen. Authentic bavarian creams are less fluid because their gelatin to custard ratios are higher than that of the doughnut filling. At a semi-solid state under cold temperatures, the hydrolyzed collagen fragments in the gelatin increase the viscosity and the rigidity of the custard. Hence, try piping a true Bavarian cream into a warm empty doughnut. You will probably feel either a resistance in the flow of the Bavarian cream or no flow at all.

Since Bavarian creams contain gelatin, it is also easy to mistake them as mousse in the culinary context. Actually, the “mousse” layers in cakes are Bavarian creams because a true mousse does not have any gelatin. This dessert (bavarois) is not to be confused with creme bavaroise (or simply bavaroise) either. Although both words literally translate to Bavarian cream, the former was introduced in Germany by a French chef who was working in Bavaria (Larousse Gastronomique 1977). The latter is a hot crème anglaise and tea beverage that was invented in France to appease the demands of visiting Bavarian princes (Larousse Gastronomique, 1977). If the Bavarian cream mold is hexagonal in shape, the nationality changes to Russian and becomes a Moscovite (Larousse Gastronomique, 1977).

Much like ice cream, Bavarian cream can come in different flavors. The repertoire includes chocolate, strawberry, vanilla, mocha/coffee, almond, raspberry, apricot, peach, pear, pistachio, applesauce, champagne, lemon and cloves (a.k.a. perfect love), hazelnut, banana, orange, chestnut and even roses. For this blog entry, I will focus on Orange Bavarian Cream (from Mastering The Art of French Cooking) because one of its steps has a scientific aspect that is not found in other flavors – extraction of the orange flavor using sugar. The procedure may sound bizarrely sophisticated but it is simple and intelligent by design.

While laboratory techniques taught in organic chemistry may prove useful, obtaining orange oil/flavor through steam distillation or solvent infusion (soaking) of the orange rind/peel are both unreasonable and impossible to perform inside an ordinary kitchen for safety and toxicity reasons. Liquid nitrogen can be used but this method demands high costs and accessibility issues – pretty impractical for isolation of orange oil at home. Dry ice will work as a cheaper substitute but this requires high pressure and high temperature such as being done in a pressure cooker and there is the potential of the oil imparting a metallic flavor and taste. Decoction or boiling the orange peel in milk is a feasible method but the loss of orange flavor through vaporization from boiling cannot be controlled.

I was impressed with Julia’s instruction of rubbing the orange peel with sugar until the sugar is “impregnated with orange oil”. For the first time, I get to perform a kitchen method that employs solid phase extraction of an essential oil or flavor. (Well ok, Julia said preferred rubbing with sugar lumps, followed by grating the orange peel into the mashed sugar. I modified her instruction by using teaspoons of granulated sugar out of practical purposes. However, you will be able to skip the grating step.) By taking place under room temperature, sugar scrubbing is a suitable method for the extraction of the flavor in the kitchen. What is also fascinating is that I searched the Web of Science and I did not find any significant search hits on a purely solid sucrose being a solvent for extraction. (Note: I might have made a mistake in my search parameters. If I do, feel free to point it out.)

The photo above shows you the difference between orange peels before (left) and after (right) being scrubbed with sugar. Pardon my photography skills with an iPhone but you may notice yellow regions on the right orange peel. Before rubbing with sugar, the peel does not only have the orange color but the surface also feels wrinkled. When the oil is transferred into the sugar, the surface of the peel loses the orange color and thins out to a smoother layer. This is somewhat similar to skin exfoliation. The white sugar, on the other hand, will turn yellow (from the carotene of the orange peel), smell citrus (from the limonene found in oranges) and appear syrupy.

So how does this state-of-the-art method work? I suspect a domino effect of sugar-scrubbing. Rubbing introduces friction into the orange peel, the friction produces heat and the cells burst (cell lysis) from the heat to release the oil. Another possible reason behind this extraction is the accumulation of sugar in the orange peel causing the cell lysis. (Of course, I could be wrong with my speculations that these guesses have to be proven and tested.)

After all this science and linguistic talk, you are probably hungry and curious on how my Orange Bavarian Cream turned out. Though the dessert looked jiggly, the dessert was decadently creamy and smooth. Once I had a sample inside my mouth, I felt the softness that the custard was melting inside my mouth. The fluffiness of the custard made the dining experience felt like eating a cloud. The flavor was not overpowering to the sweet taste of the custard even with the combination of the orange juice, orange liqueur and orange oil. I died and went to heaven from having this bavarois and I can’t wait to do it all over again.

Orange Bavarian Cream (Taken from “Mastering The Art Of French Cooking”)

Orange Flavoring
2 large brightly colored oranges
2 large sugar lumps (2-3 teaspoons of granulated sugar)
1 1/2 tablespoons gelatin powder

Custard Sauce
7 egg yolks
1 cup granulated sugar
2 teaspoons cornstarch
1 1/2 cups boiling milk

Egg Whites
5 egg whites
1 pinch of salt
1 tablesppon granulated sugar
Ice bath

Orange Flavored Whipped Cream
1/2 cup whipping cream
2 tablespoons orange liqueur

Garnish (optional)
Peeled orange segments

1. Wash and dry the oranges. Rub the sugar over the skin of the orange. If lumps of sugar are being used, mash the sugar lumps and zest the orange peel into the sugar. If granulated sugar is being used, the oil will definitely get into your hands. To solve this problem, scrape the oil from your hands with a spatula.
2. Squeeze the orange juice and sprinkle gelatin over the orange juice.
3. Beat the egg yolks into the orange flavored sugar. Gradually add the granulated sugar while beating until the mixture is pale yellow. Beat in the cornstarch.
4. Pour the milk into the beaten egg yolk mixture in a thin stream of droplets.
5. Return the resulting custard sauce into the saucepan. Thicken the mixture over moderate heat. Make sure to stir with a spoon or a spatula. (Tip: To find out that the custard is thick, coat the spoon or spatula with the custard. If you run your finger on the custard sauce and the coating does not fill the line that you made, then the custard sauce is thick.) Do not overheat or overcook otherwise, the egg yolks will curdle and will separate from the milk.
5. Dissolve the orange juice-gelatin mixture into the custard sauce immediately after removing the saucepan from the heat. Pour into a mixing bowl.
6. Beat the egg whites, salt and sugar until stiff peaks are formed. Fold the egg whites into the cooling custard.
7. Transfer the bowl to the ice bath. Fold the mixture frequently to prevent separation of the custard from the egg whites. When the mixture is cold, set aside.
8. Place a mixing bowl containing the whipped cream under ice bath. Beat the cream until volume doubles.
9. Fold the cream and orange liqueur into the custard.
10. Transfer the entire Bavarian cream into mold. Cover with wax paper and chill the mold for 3-4 hours or overnight.
11. To unmold, dip the container into hot water for one second. Run a long thin knife around the edges of the cream. Reverse on the serving platter.
12. Garnish with orange segments.

 

Ode to Brussels sprouts

No, this is not a poem about the tiny cabbagehead. It’s a short note about this particular cruciferous veggie and how it had suffered injustice in the hands of too-eager cooks.

Brussels sprouts have been described in not so flattering terms as a detestable vegetable in terms of texture and taste, as stereotyped by kids hating the stuff more than broccoli. And this stereotype only exists in the Western side of the world, as it is very rare (or even nonexistent, as far as I know) in Asian cuisine.

Recently, this has been the case: Asian grad student (i.e., me), meet Brussels sprouts–Brussels sprouts (or in Dutch, spruiten), meet Asian grad student. Grad student goes “WTH is this tiny cabbagehead?!”

How can something so tiny and cute be so maligned in pop culture? One word: overcooking. This little one is soooooo easy to overcook.

(Courtesy of Wikipedia, because my camera died on me)

(Courtesy of Wikipedia, because my camera died on me)

This tiny veg has sinigrin, which is responsible for the disagreeable taste of overcooked sprouts (it gets degraded in high heat, splits off from its sugar molecule…and did I tell you that it has a sulfur atom or two in its structure? Hence the smell and taste).

But…its propensity to be easily overcooked is a plus for a harried grad student–this only means that it has an absurdly short cooking time, so whipping up a simple leafy side dish (or a main) is just under 8 minutes of cooking time (go past it–ugh!).

Here’s one treatment of this veggie that I did, without looking for an actual recipe. My kitchen philosophy lately is–grab whatever and go.

Simple sauteed sprouts in sesame oil
Materials
- Brussels sprouts, bases chopped, spotty/brown/hole-y outer leaves removed (if head is too big, cut in half)
- Garlic, minced (amount is variable, but I love garlic!)
- 1 Tbsp (or thereabouts) peanut oil or RBD coconut oil (or any mild, bland oil)
- Black sesame oil
- Salt and pepper, variable

Methodology
- Blanch prepared sprouts in boiling salted water for 2-3 mins. or until the heads turn bright green. Pour in a colander and cold-shock the batch with cold running water from the tap. Drain well.
- Heat peanut or coconut oil in a big frying pan or wok (medium high). Toss in minced garlic until it turns light golden brown and the garlicky smell is apparent.
- Toss in the drained sprouts. Season with salt and pepper. Stir-fry them for 2-3 minutes, or until they are lightly coated with hot oil and garlic.
- Drizzle with black sesame oil, toss and remove from heat immediately.

Discussion
Cooking time. When you do the math, the total cooking time is 6 minutes, tops. That’s little under 8 mins, after which you’re past the point of no return and the veggie turns into something hateful and a complete waste of time and resources.

Cold-shock. This is a measure to ensure that the veggie is not overcooked. Sprouts are notorious for storing heat in their compacted leaf-heads, so even though they’re drained from the blanching liquid, the heat will cook them from the inside. As you may notice, I did not score the bottom of the sprouts before blanching–damaging the veggie in that manner increases the risk of overcooking. Might as well cut the sprouts into half before blanching, so you’d get to see how the inside looks while cooking.

Peanut or coconut oil? And what’s RBD? Peanut oil is actually tasteless. And can withstand high heat without getting degraded. Coconut oil is better–that is, RBD (refined, bleached and deodorized) coconut oil because it doesn’t degrade into trans-containing oil at high heat and is bland. Using a mild, bland oil brings the natural flavor of the key ingredients (sprouts, garlic, sesame) to the fore.

Properly cooked sprouts taste–? Wonderful. Au naturel, it has a pleasant nutty flavor to it, which complements well with the aroma of fried garlic and sesame oil. The bitterness is absent, or, if you choose to focus on it, a very minor note that gives an earthy dimension to the dish.

I like pairing this dish with a simple main one–like pan-grilled sausage, or a serving of well-aged chicken-and-pork adobo. And lots of rice, of course.

 

Apple Snow: Golden and Delicious

October is not just a bacchanalia of overflowing beer in pubs, bars and festivals. October is certainly the time of the year where you can keep the doctor away. Why? October in the United States is National Apple Month according to the U.S. Apple Association. As autumn starts to shed the leaves of the deciduous trees, apples also become ripe for picking in fruit orchards. Because it’s the season of the apple, they will also cost cheaper in groceries (at least here in the United States) and they will also taste a lot better than apples picked “outside” of its season.

If you are a fan of mythology, literature, the classics and arts, you would probably notice that apples typically have become either a sacred, indulgent or seductive symbol. The golden apple of discord caused three Greek goddesses to clash and compete in a beauty pageant title of being the “fairest one”, indirectly precipitating into the Trojan War. The “tomboy” Atalanta lost to Hippomenes in a race after the latter threw three irresistible golden apples of joy in order to outrun her in exchange for her hand in marriage. The golden apples of Hesperides/Hisbernia bestow immortality in Greek mythology and eternal youth to the gods of Norse and Celtic mythology. Renaissance painters use apples in their paintings as emblems of condemnation and redemption in their re-imagination of Biblical stories from the fall of man to sin to the salvation by Jesus’ loving sacrifice- depending on the persona who holds the apple.

As of this month, there are 7,500 cultivars of apples based on the place of origin and their ancestors. This does not only mean that there are 7,500 apple genomes out there but this may also imply that if your tongue has a has a detection limit of 1/7500, then tastewise, it would be able to distinguish how subtly different the cultivars are. Of course there is no human tongue that is gifted enough to achieve that feat! That is why these apple cultivars are gastronomically classified according to their use – eating, cooking and cider. Not that you have to be anal retentive, but you need to plan ahead what apple cultivar you are going to use in your recipe before you buy them in the grocery.

I must confess though that I am not much of a fan of apples, I had only come to appreciate them during the celebration of National Apple Month thanks to this marvelous recipe – Apple Snow. This dessert is simply a combination of applesauce and egg whites as the latter are beaten into stiff peaks. What’s pretty slick about this dish is how the applesauce and egg whites complement the taste and the texture. The applesauce gives the mildly zesty flavor and the sweet taste while the egg whites are responsible for the creamy texture. The addition of caramel sauce finally enhances the rich taste.

But how do you address the issue of apple cultivar for the applesauce? I highly recommend the Golden Delicious (United States) which according to the U.S. Apple Association is third most popular cultivar. While the Granny Smith (Australia) is ideal for withstanding the cooking temperatures, it is not suitable for this dessert because of high malic acid content, resulting to a sour taste (Wu J, Gao H, Zhao L, Liao X, Chen F, Wang Z, Hu X. "Chemical Compositional Characterization of Some Apple Cultivars" Food Chem., 2007, 103, 88-93. doi:10.1016/j.foodchem.2006.07.030). In fact, I learned this the hard way from the first time I tried preparing the applesauce from Granny Smith apples. Golden Delicious is also advisable for the applesauce not only because its low malic acid content has been consistently reported from literature but also because it contains a high sugar content in comparison to sorbitol-devoid apple cultivars like the Gala (New Zealand) and the Gravenstein (Denmark) (Hecke K, Herbinger K, Veberic R, Trobec M, Toplak H, Stampar F, Keppel H, Grill D. "Sugar-, Acid- and Phenol Contents in Apple Cultivars from Organic and Integrated Fruit Cultivation" Eur. J. Clin. Nutr., 2006, 60, 1136-1140. doi:10.1038/sj.ejcn.1602430). Finally, it just makes the experience of enjoying your apple snow both golden and delicious!

Apple Snow (taken from “The Way To Cook” by Julia Child)

Ingredients:
6 to 8 Golden Delicious apples
1 medium lemon
1/2 teaspoon cinnamon or 1 cinnamon stick
1/2 cup sugar or even less
1/2 teaspoon pure vanilla extract
4 large egg whites
1/2 teaspoon cream of tartar
1/2 cup homemade caramel sauce

1. Wash, quarter and core out the seeds of the apples. Keep the peel in the apples to retain the flavor and the body of the sauce.
2. Place the apples in the saucepan along with the zest of the lemon and the cinnamon. Sprinkle the apples with lemon juice. Cover the pan and soften the apples under moderately low heat for 30 minutes. Make sure to stir and mash them frequently.
3. Remove from heat. (If you are using the cinnamon stick, remove the cinnamon from the saucepan) Transfer the apples into a food processor, purée and return the applesauce into the pan.
4. Boil the apple sauce, gradually adding the sugar. Stir in the vanilla.
5. Cover and chill inside the refrigerator for at least one hour.
6. Set the electric mixer at moderately low speed and beat the egg whites until they start to foam. Add the cream of tartar and increase the speed until stiff shining peaks are formed.
7. Reduce the speed and add the apple sauce into the beaten egg whites. Raise the mixer speed again until the mixture is stiff enough to hold its shape.
8. Drizzle or layer with caramel sauce any way you like it

Caramel Sauce
1/3 cup sugar
5 teaspoons water
1/3 cup cold heavy cream
3/4 teaspoon vanilla extract
Salt

1. Blend the sugar and the water in a saucepan and let them simmer.
2. Remove from heat and swirl to completely dissolve the sugar.
3. Return the pan to the stove at moderately high heat and boil for several minutes. Make sure peek into the pan. Once the bubbles look thick, uncover the pan and swirl it by its handle.
4. Boil for a few more seconds. Remove from heat and continue swirling.
5. When caramel has cooled but remains in the liquid state, add the heavy cream.
6. Whisk over moderate heat until the congealed caramel dissolves. Stir in salt and vanilla.

 

Suprême – The Breast Taste Of Chicken

Thanks to the strenuous workload of graduate courses, research and teaching. My food blog entries were as dead as Friedrich Nietzsche’s definition of God from his book “Die Fröhliche Wissenschaft (The Gay Science)”. Now that my graduate school obligations are temporarily over, it’s time to resuscitate my contributions of blog entries to Phood Journal.

Perhaps it’s an appropriate time to talk about breasts…chicken breasts…

To be honest, breasts are not my favorite part on a chicken. My order of preference when I am, say, given a half-serving of chicken or any poultry/game bird is thighs, legs, wings and breasts. I am fully aware that health and fitness buffs will contend with me but chicken breasts tend to have a very dry and bland texture. It doesn’t help too if the chicken bought from the market turns out to be an old and ailing chicken because the meat can be VERY tough. To open some gastronomic scars of my childhood, I found myself having a difficult time chewing and swallowing, and to some point would prefer regurgitating, the meat of the black chicken boiled in some weird Chinese plant extracts not because of the bitter taste coming from whatever alkaloid or natural product is found on that soup but rather the texture of the breast meat is just too DAMN dry and bland.

Then again, the chicken breast should not shoulder the blame for its taste and texture. Its prolonged exposure from the heat of braising, boiling or roasting has to compromise with the duration of completely cooking the softer, fattier and juicier red meat found on the thighs and the legs. The rule of thumb of treating chicken breasts (or any breast coming from any poultry or gamebird) with love is that you DO NOT OVERCOOK them UNLESS they come with the other parts. Plus, time is an advantage too for graduate students like me because the length of preparation can only take 15-25 minutes especially if you are aware of the “cooking parameters” that will maintain the juicy and exquisite taste and softer texture.

Paraphrasing French cuisine from Julia Child, the raw breast of a chicken is classified according to the presence of the wing, skin and the bone. If the upper part of the wing is present, then the entire slab is called a “côtelette” or simply (in English) the cutlet or the chop of the chicken. If the breast comes both skinless and boneless, then the chicken breast is called a suprême. However, a suprême is NOT ALWAYS a suprême because the definition of a suprême encompasses the cooking time and hence the taste and the texture of the flesh. If the “suprême” is overcooked, it becomes nothing more but the bland, dry and tough white chicken meat – similar to a prolonged chemical reaction that leads to an undesirable product. Instead, an actual suprême should be cooked in 205°C (400°F) for 6-8 minutes only – NOTHING LONGER NOR HOTTER.

Based on my first experience of cooking and eating a homemade suprême, the final grade that can be given to a suprême borderlines between “E” and “F” for EXQUISITE and FANTASTIC respectively. Cooking is also short and simple that the anticipation of eating can only be delayed by the preparation of the sauce. The flesh is white in color just like your white chicken meat. However, the taste is so juicy and the texture is so soft that it’s like eating the drumsticks and thighs – my conventional favorite parts on a chicken.

I think from now on, the breast (in the form of a suprême) has become my GUILTY PLEASURE.

Chicken Suprêmes Recipe (taken from “Mastering The Art Of French Cooking” by Julia Child)

Ingredients:
4 fillets of chicken breasts, boned and skinned
4 tablespoons of butter
1/2 teaspoon of lemon juice
Salt
White Pepper

1. Preheat the oven at 205°C (400°F).
2. Season the chicken with salt and pepper. Sprinkle with lemon juice. Set aside.
3. While the chicken is being marinated, melt the butter on a skillet or a flame-proof casserole under medium to high heat until the butter starts to foam and bubble. (Optional: The foam can be removed by scraping with a spoon giving the clarified form of butter.)
4. Roll the chicken breasts in butter QUICKLY and remove the skillet or casserole from heat.
5. Cover the breast with wax paper or aluminum foil.
6. Place the skillet or casserole inside the oven and bake for 6-8 minutes.
7. Remove from oven and transfer the breasts immediately to a warm platter. The leftover butter in the skillet or casserole can be used to prepare the sauce of your liking.

 

Culinary Instrumentation 101: The Trusty Food Processor

I don’t know how much blood I have lost from accidentally getting cuts on my fingers with either a chef’s knife or a cheese grater over the past two months. All I know is wherever the site of the bleeding is, it’s too far away from my entrails, unless I perform hara-kiri. Aside from that, it just occurred to me two weeks ago that julienning and mincing meat and vegetables into strips or pieces with a knife seemed a tedious and time-consuming process for a graduate student who should spend more time pursuing erudition rather than olfactory and gustatory indulgence.

As time is more important than money, I decided to invest on a substantially “expensive” instrument – the food processor. Well, it was substantially “expensive” because I bought the Cuisinart brand with a 7-cup capacity. I bought it brand new from an Ebay auction at 66 USD – 20 USD shipping charge included (but this is already considered cheap because the 7-cup Cuisinart food processor costs 100 USD on Amazon or on grocery stores.) I don’t want to sound like a beauty pageant contestant but I have to say this. I personally believe that every graduate student studying ALONE and ABROAD should own one. Here are my Top 5 reasons justifying my worthy investment:

1. Versatility: A food processor is like the entire set of food preparation apparatuses crammed into one machine. It does not only chop and mince. Provided that it comes along with the shredding and slicing discs, it can grate, julienne and slice too. You can also use it for mashing without you complaining about the lumps produced from using a fork. This feature also allows you to prepare soups, sauces, stuffings, dressings and garnishes. (Limitations: It does not dice.)

2. Automation: A food processor is like a spectrometer without the detector. Not that I am lazy in cooking but as a graduate student, time is of the essence. So just plug your food processor and and individually put whatever vegetable you need for cooking. Press the button. Presto!!! You are done in 2-3 minutes as opposed to using a knife which will take you 10-15 minutes to get the job done.

3. Safety and Protection: One cool feature of the food processor is that it is covered. That way it protects your eyes from whatever lachrymose vapors released during chopping. (This is somewhat analogous to a pair of laboratory goggles except you don’t have to put on it because it’s the food processor that wears it.) In addition, to avoid any future possibility of getting cut, you can skip washing the food processor blades with sponge and detergent. Instead, use the dishwasher.

4. Consistency This feature will come into play if you need to prepare scalloped vegetables. What your food processor does is that it slices your vegetables evenly, maintaining the consistency of food texture upon cooking. (Sidebar: Not advisable if you are julienning vegetables for garnish.)

5. Practicality: If you are done with your graduate studies and you plan to go back to your home country that you no longer need it, sell it via Ebay or Amazon. That way, you will be able to partially retrieve your money.

In other words, the food processor is your trusty kitchen sidekick.

 

Hamburger Science: Why I Will Probably Never Eat At Another Burger Joint (Unless Starvation Calls For Desperate Measures)

If you were asked to name the ultimate American food or fast food on the game show “Family Feud”, there’s no doubt that hamburgers will probably be the top survey answer. Perhaps to the food amateur, he/she will be looking for the ground “ham” component from the burger patty even though the former is a slab of salt/sugar-cured pork while the latter comes from minced beef chuck. Hamburger was actually a German word coined after the city of Hamburg which served as an important Russian trade center of steak tartare (but that’s another recipe) during the last century of the Holy Roman Empire.

Even before I became a Julia Child fan, I had this curiosity on preparing and cooking hamburger patties. Most people consider the simplicity of its preparation because you just mix ground beef, onions, salt and pepper and fry them on a thin film of oil. Voilà! You have a burger!!! One of my friends gave me an account that her mom used to prepare hamburger patties before but they had a tendency to contract even before cooking that you don’t get your appetite’s worth at all. I had also made several food trips in the Philippines (where I come from) to search for the best burger joint. I even watched an episode of The Oprah Winfrey Show just to find out the The Top Ten Best Burgers in the U.S. (If my memory serves me right, the best burger in America comes from a sirloin burger joint somewhere in Chicago)

Aside from simplicity, students like myself take into account the cost of a homemade burger versus a burger ordered from a fast food chain or restaurant. Assuming you don’t have to pay any state tax, service charge or value-added tax from your restaurant bill, the cost will still be at least thrice the price of making your own hamburger sandwich from the convenience of your own home.  But, here comes a big (and all-caps) BUT!!! Advantages of simplicity and cost obviously compromise the ideal flavor, texture and taste. The patties greatly contract even before frying as mentioned above. They dry up by losing their juices upon frying. No matter how iconic the hamburger is to U.S. culture, Americans (no offense) have probably underestimated its simplicity. So where does the problem lie? Lipid/fat biochemistry.

Fat inside the ground beef works two ways. Being hydrophobic or water-fearing, the presence of fat retains the moisture and juices inside the meat, therefore slowing down the dehydration/contraction process. It also adds flavor to the meat during heat-induced hydrolysis and/or oxidative cleavage.  However, if fat degradation takes place at a faster rate before or during cooking, then dehydration will occur quickly too because water is less trapped due to reduced fat levels. To solve this problem, fat content of the meat is increased by adding sour cream, thus, keeping your meat swollen and moist during cooking. This is the scientific basis behind Julia Child’s hamburger recipe from The Way To Cook.

I have a confession to make. I was pretty unsure of what might happen while I was preparing the entire hamburger meat based on Julia Child’s recipe. It turns out the result was awesome. The patty itself was so thick and fat as seen on both pictures. If you ask me about the taste, it was juicy and mouth-watering that I have to fry another patty to satiate my appetite. Honestly (and I don’t mean to brag), the burger was a lot better than the burger joints here in the U.S. or those from the Philippines. Also, if you are cutting costs, hamburger is probably the practical way to go. I finished the entire hamburger meat for 6-7 dinner meals at an estimated total cost of 10 USD. That’s spending around 1.50 USD for one night of fine dining without sipping a glass of red wine.

Now that’s a HAMBURGER!!!

Burger Patty Recipe (taken from “The Way To Cook” by Julia Child)

Ingredients:
1 1/2 pounds (681 g) of ground beef
1 egg
2 tablespoons of onion, grated
2 tablespoons of sour cream
1 teaspoon of thyme (fresh or dry) or Italian seasoning
Salt
Pepper
Cooking oil
Flour

1. In a large bowl, season the ground beef with egg, grated onion, sour cream, thyme, salt and pepper. Mix thoroughly.
2. Divide them in any way you want to and shape them into round patties.
3. Film the frying pan with cooking oil under moderately high heat.
4. As the pan undergoes heating, lightly dredge each side of patty with flour. Fry each patty two minutes in one side and two minutes on the other.
5. If hamburger is squashy, then it is rare. Once the meat starts to bounce when pressing with a turner or your finger, it is medium rare. The hamburger patty is well done when it doesn’t bounce/spring back.

 

Practical advice to the food storage junkie

You bought a carton of eggs last month and forgot when the expiry date was. Two weeks ago, you used up half. Today, you have nothing in your fridge and you have no time to prepare anything else cuz because you have to get on with writing your paper. Eggs are there. Hmm a quick sunny side up or maybe a Tamagoyaki. But then are the eggs still ok?

If you’ve been lurking in Huffington Post, you would have caught wind of this website called StillTasty, Your Ultimate Shelf Life Guide. No, our blog is not paid to advertise them. I just find the site extremely useful especially since sometimes I don’t know how long I can keep food in for.

What I really find nifty is that they try to cover as many situations as possible. Because you know that fresh, raw, cut up peaches will keep differently compared to fresh, raw, whole peaches.

Opened a package of cottage cheese? It’ll keep for over a week if you keep it in the refrigerator in a sealed container. Pop it in the freezer, and it’ll be ok for the next three months. Just remember, the longer they’re stored, the less likely they’re going to be tasty.

 

Egg-citing? Egg-xotic? Tamagoyaki!

Aside from instant food, a quick, reliable complete-food source for a grad student is…egg.  Eggs.  Now, before you whip out your wellness-and-health magazines and condemn eggs as unhealthy, think of this in another perspective: cholesterol aside, eggs contain enough protein and fat to tide a starving person for a day.

(Also, eggs contain vitamin D—and it is hard to get a regular dose of sunshine here in Europe, so you might as well eat eggs.)

Yes, eggs are nutritious, and, cooked as is, very bland.  This blandness makes eggs very versatile in cooking, as it can take any kind of seasoning (not to mention cooking styles).  There’s the simple sunny-side up, there’s Julia Child’s omelet…and there’s tamagoyaki.

What is tamagoyaki?

Simply put, it’s just an omelet. A Japanese sweet rolled omelet.  Usually found as a topping in sushis, or as a bento item (with octopus-cut sausages and cute baby veggies).  What makes this one different from other omelets is the distinct sweet-salty taste from sugar and soy sauce.  Nothing screams Asian (heck, even Japanese!) than this flavor profile for an EGG dish.

And, for an omelet, it’s pretty easy to do. No need for fancy tosses!

Materials and Equipment

• 6 medium eggs
• 1 tsp soy sauce
• 1 Tbsp sugar
• Chives, finely chopped (optional)
• Cooking oil
• Silicone brush / a square of kitchen towel
• Silicone turner
• Non-stick pan

Methodology

• Crack eggs in a large bowl.  Add soy sauce and sugar. Beat with a fork or a pair of chopsticks…but never with a wire whisk (you don’t want air bubbles in your mix!).
• Heat the non-stick pan at medium-high. Brush a thin layer of cooking oil on the surface.  Wait until the pan is hot enough (guesstimate by holding an open palm 1” above the cooking surface).
• Pour a small amount of beaten egg in the pan, letting it spread into a thin layer.  Wait until the rims set and the egg-layer is not that fluid or runny.
• With a turner (or a pair of chopsticks, or a fork), lift the nearest side of the omelet and begin rolling AWAY from you.
• Brush some oil on the now-clean surface of the pan before pouring another layer of beaten egg (lift the egg roll to let the egg mixture spread over the whole pan).  As soon as it sets, roll the egg back towards you.
• Repeat the previous three steps until you run out of beaten egg.
• OPTIONAL: if you have finely-chopped chives, sprinkle some on the egg layer before it sets, then roll.
• Slice the roll to show the spiral cross-section before serving.

Results and Discussion

No salt? Other recipes call for at least a teaspoon of salt for the mixture, aside from soy sauce.  I opted this out if only to cut the sodium intake.

Can I use other non-egg ingredients aside from chives? Yes, of course.  Finely shredded leafy veggies like spinach or cabbage, or even thin meat flakes can be used.  Or strips of nori.  Or, my personal preference is tamagoyaki WITH CHEESE (all the more I leave out salt, since cheese can be salty) and ham.

Can you eat this as is? Well, you can, if you add other ingredients like vegetables or meat.  It’s like your regular omelet, except that it’s rolled instead of folded (it’s easier to roll eggs than to fold them)…and is salty-sweet.

Wrapping up

Nothing screams fast food as an egg omelet.  And serving it as a tamagoyaki gives this simple, nutrient-dense dish an interesting spin for a hungry grad student.

And who says the only Japanese food a grad student can have is instant ramen?

The Cookie Crack’d from Side to Side – Chocolate Crinkles

No, this is not a spin-off of an Agatha Christie novel.  Neither is this a serious, original recipe post (you can get it here), but more of a running commentary about making and eating this sweet goodie.

Chocolate crinkles are very much popular back in Manila.  This particular cookie is a regular item in school cafeterias, holiday bazaars and specialty bakeries—but not on a supermarket shelf, since it is too soft and fudgy to withstand rough commercial handling.  Its soft, fudgy, chocolate-y core hidden beneath the fine dusting of confectioner’s sugar is the dark, sweet secret of its popularity.

Perfect crinkle shot by Kookie

What’s so nice about baking chocolate crinkles is its simplicity—no need for cookie cutters, rolling pins and what-have-you.  You can make the dough way ahead of time(it is, in essence, a “dump-everything-and-mix” technique) and store it in the fridge; the dough itself has little moisture, hence the “crinkling” during baking (and storing it in the fridge removes more moisture, thus more “crinkles” on the cookie surface).  Perfect go-to baking recipe for a grad student with a sweet tooth, and an instant crowd-pleaser.  I mean, who doesn’t like chocolate?

Just a few tips: you can go “generic” with the base ingredients like flour and sugar, and even butter (provided that you live in Europe, where standard butter here is “European” butter, with at least 80-85% fat)…but never, EVER scrimp on chocolate!  For obvious reasons, of course.  And don’t hesitate to experiment with cookie sizes—the recent batch I made were “mini” crinkles, which paired well with vanilla ice cream.

Yes, nothing like chocolate, vanilla and sugar to win everyone’s hearts.  Just watch your insulin levels, though.

 

A PhD 15-minute gourmet – Lemon, Butter and Fish

Anyone up for a quick fish dish that looks sophisticated YET is very simple in terms of ingredients and cooking AND is actually nutritious?

I was craving for that sort of dish more than a month ago, which led me to the nearby ALDI Markt (yes, there IS an ALDI Markt near my place, so my cheapskate heart was glad) to pick up some Alaskan pollack and Norwegian salmon fillet.  And a bottle of citroensap (lemon juice).

Fish. And lemon. What I was missing a lot that day was ADMU’s Blue&Gold café’s famous Grilled Blue Marlin in Lemon-Butter Sauce, but since I didn’t want to fuss too much about making the actual lemon-butter sauce, I just took those two flavor ideas together and came up with a simpler version.

Lemon-marinated, pan-seared Alaskan pollack fillet (or Lemon+Butter+Fish)

Materials

• 1 piece Alaskan pollack fillet (or any fish fillet, really)
• Juice from half a lemon (or  approx. 4 Tbsp lemon juice)
• Salt and pepper, to taste
• Ginger powder
• Dried minced garlic
• 1 Tbsp butter

Methodology

• Thaw fish fillet, draining off excess fluid.  Place in a shallow dish then marinade it with the rest of the ingredients (for at least 15 minutes) except for butter.
• On a non-stick pan (stove set to medium-high), melt butter.  As soon as the melted butter clarifies, slide the marinated fillet in the pan. Let it brown for at least 5 minutes, then flip the fillet to let the other side brown for another 5 minutes or so.
• For the final “pan-seared” look, drizzle the fillet (while in the pan) with the lemon marinade and a small knob of butter.  While sizzling, remove pan from heat.
• Serve fillet with buttered vegetables and a carbohydrate-source (hot, fluffy rice OR newly-cooked Belgian fries for a proper fish-and-chips dish)

Results and discussion

Preparing the marinated fillet. To save time, the fillets can be marinated in advance—lay the slices flat in a Tupperware box, seasoned and marinated with lemon juice, then stored in the freezer.

Actual cooking time? At least 15 minutes, if the fish fillet is thawed properly.  Cooking at medium-high heat has its disadvantages to half-thawed fish—outside, the fillet is just “too brown” (read: burnt) while inside, the meat is barely cooked.  And I say at least, because I am a freak when it comes to well-done meat slices (fear of bacteria, really).

Careful with the lemon! Let us just say a too-hot pan with fish and butter will not take well to the lemon marinade if the said pan is still on the stove.  Did that once and ended up with a black oily mess that smells like I buttered my lemon fruit and stuck it in the oven at 350 deg C.  Butter can quickly turn brown upon addition of an acid (this case, lemon juice), especially in high heat, which is something I wanted to exploit to give the fish fillet a “pan-seared” look.

Fish = acid PLUS ginger. I can eat anything…as long as the odd “fishy” smell and taste are neutralized by the addition of acid (lemon or vinegar) tempered with ginger.  And lemon + ginger taste good together.

Wrapping up

I don’t think I can source out blue marlin anytime soon and I’ve yet to make a proper lemon-butter sauce.  But cooking bland, white-fleshed fish like the Alaskan pollack in this manner gave it a little oomph because of the lemon (with ginger undertones) and butter.
