circletimessquare writes "Using ingredients usually relegated to the lower half of the list of ingredients on a Twinkies wrapper, some professional chefs are turning themselves into magicians with food. Ferran Adrià in Spain and Heston Blumenthal in England have been doing this for years, but the New York Times updates us on the ongoing experiments at WD-50 in New York City. Xanthan Gum, agar-agar, and other hydrocolloids are being used to bring strange effects to your food. Think butter that doesn't melt in the oven, foie gras you can tie into knots, and fried mayonnaise."

    Heston Blumenthal's Kitchen Chemistry series (which unfortunately didn't make it) was a lot more interesting than this article. You can even find torrents of the pilot episodes [thepiratebay.org]. I wish that series had been picked up and continued because there were some very interesting subjects, like the reasons behind certain flavours simply being unable to mix (basil and coffee, for example) as well as an everyman's guide to how the chemistry worked. As innovative as Blumenthal can be, there's no way I'm shelling out £300 for a meal at his restaurant.

Very entertaining but perhaps not entirely practical - in one of his recipes he made ice cream using liquid nitrogen, and his suggestion for the home enthusiast was to use dry ice instead.

        Not really. Your idea only makes sense if you did want to reduce the pressure for some other reason - selectively evaporate stuff - like in fractional distillation.

        For temperature control, you use a thermometer/thermostat with feedback.

        For example you can soft boil eggs in an oven. You just need to calibrate your oven well. Then if you set it to 65 degrees C and stick the eggs in for an hour, they still won't be hard boiled :).

          -certain- things must be just-so, others can be experimented with without ill effects, or easily be corrected if you get off-track. The reason cooking is hard for beginners is that they're not aware of which things belong in which category, so they stress the stuff that isn't actually that critical, or are too sloppy on the few spots where you really need to do it -JUST- so, or both.

          If you're making bread it -matters- if the temperature of your liquids is 30C, 38C or 50C. If you're making lasagne it does -not- matter, well theoretically you may need to leave it for 3 minutes longer in the oven... If you triple the amount of chili in your chili con carne the result may be non-edible for non-dragons, if you triple the amount of estragon on your pizza, you get sligthly-more-estragony pizza, nobody will even really notice. (it'll taste a bit different, but not inedible, probably not even bad)

          If you're making buns, they'll in general (up to a point anyway) be better if you work the dough more vigorously, perhaps letting them rise multiple times with workings of the dough between. To the contrary, if you're making any kind of sponge-cake where the airness comes from beaten eggs, then you should stir as little as absolutely humanly possible after adding the flour, since otherwise you'll beat-out all the airiness.

          So, in short, cooking ain't in general hard at all. There's certain details that you need to pay attention to. It takes some practice or teaching or both to learn which, precisely, that is. You probably need to mess up these things a few times to really learn them. Most people I know have tried the trick of baking pizza with too-warm water once -- most people don't need to do that more than once to get the idea....

            It sounds like you've just described most activities that people outside those activities find hard.

            Auto mechanics ain't in general hard at all. It's just knowing which nuts and bolts to undo, in which order, and on which part.

            Assembling one's own computer ain't in general hard at all. It's just knowing which parts are compatible with which parts, plugging components into each other, and knowing when you are in danger of frying a component due to static electricity and when you aren't.

            It reminds me of an anecdote I've heard attributed to Henry Ford but couldn't find after an exhaustive 30 second search on Google. Henry had some equipment that was malfunctioning, and his engineers couldn't figure out what was wrong. He decided to call in the guy, let's call him Bill, who had designed the equipment. Bill spent 45 minutes working on the equipment, got it working, and left. A couple weeks later Henry received an invoice from Bill for $10,000. Henry called Bill up and said, "I know your time is valuable, but don't you think $10k is a little much for twirling a few knobs and bolts?". Bill agreed and said he'd adjust the bill. Henry got an adjusted bill soon afterwards that said, "Adjusting a few knobs and bolts: $1000. Knowing which knobs and bolts to adjust: $9000."

            So I've babbled on enough, and I agree with you that once you get into cooking, much of it isn't that daunting, but neither are most other pastimes once you've figured them out.

        At the same time baking isn't that precise - there is quite a lot of room for wiggle. This is most noticeable when it comes to heat, as VERY few ovens give you the ability to control the temperature to a single degree, let alone a fraction of one. Also noticeable in that you don't have to plug your heat and time into a formula to account for difference in air density (usually due to distance from sea-level).

        The chemical reactions that make a cake or a loaf of bread is not very different than making a vinegar/baking soda volcano.

        Whist baking cakes does tend to rely on sodium bicarbonate reacting with an acid (usually tartaric acid) to produce CO2, and also to a lesser extent on the natural raising agents in eggs, bread is completely different. Bread is risen by the carbon dioxide produced in anaerobic respiration performed by yeast (the same as when brewing), and the alcohol produced then evaporates off when the brad is baked.

        That's nothing but a new name for an age old process.

        By this logic, it should be called food alchemy. Believe it or not, just because you don't know the difference doesn't mean that there isn't one.

        The process of adding heat to reagents (a.k.a. cooking) is in itself a chemical process.

        One which essentially nobody - including professional food chemists - understands in even the simplest of organic foods. Cooks sure as hell don't - they know how long to fry it, and generally what's going to happen when you fry it, but one mention of the single most prevalent chemical in the reaction, phospholipthene, and you're greeted with a bunch of glassy looks.

        You might as well argue that being a coffee barista is a chemist's process too; it turns out that frothing milk - the process of building a colloid from the 40 or so whey caseins and half dozen fats in cow's milk is more complex than broiling steak, baking bread and aging tofu put together. 'Course, they just get a five minute training on it, like a cook does: use at least four ounces of milk, keep the milk as cold as you can, keep the steam a quarter inch under the surface. That's cooking: being oblivious of the chemistry, and focussing on the food.

        Molecular gastronomy is a powerful tool for cooks, but it isn't cooking, and it's essentially useless on its own.

        Take baking, for example. For those who've never tried it, baking is a very precise exercise.

        Nonsense. You can vary the amounts of almost every ingredient in a bread dough by 200% or more and it'll still be just fine.

        You have to add precise amounts of reagents, mix them together in a certain order, and add a precise amount of heat for a precise amount of time.

        Have you ever baked? At all? Do you know what a bagel actually is? Did you know that if you want a crusty bread, you can just brush the half-cooked loaf with water, then oil, and increase cooking time ~20%? None of those three things you said are true; baking is, with notable rare exceptions like souffle, one of the most forgiving and imprecise forms of cooking there is. You almost couldn't have chosen a less appropriate example, short of slow-roasting meats or curing foods over months.

        That whole undertaking is very chemical in nature.

        What, because you need a specific amount of a specific stuff and you have to put it in at the right time? By that logic, putting gas in your car is a work of chemistry, as is washing your clothes (and let's not even get started on mixing paint.) Just because something is made out of chemicals doesn't mean using it is chemistry. Humans are made out of chemicals, too, y'know. In fact, everything is. You might want to look up the word "tautology."

        If you time it wrong, add the wrong amount of heat and/or reagents, then you're going to end up with some pretty disastrous results.

        Ah, so ironing my clothes is chemistry, using hot glue guns is chemistry, soldering is chemistry and alka-seltzer is chemistry. Got it.

        You're one of those people who argues that anything you can describe a process for is art, aren't you?

        The chemical reactions that make a cake or a loaf of bread is not very different than making a vinegar/baking soda volcano.

        The chemical reaction in vinegar volcanoes is a hydrogen exchange salt reaction.

        CH_3 COOH + NaHCO_3 --> CH_3 COONa + H_2 CO_3

        There are more than two hundred chemical reactions involved in bread, but the one you're probably thinking of is the yeast breaking sugar and alkali into alcohol and carbon dioxide. This is two primary reactions with dozens of variants:

        C_6 H_12 O_6 + Therm. --> 2 (C_2 H_5 OH) + 2 CO_2

        2 (C_3 H_6 O_3) + K_2 CO_3 --> 2(KC_3 H_5 O_3) + H_2 O + CO_2

        The two processes are, in fact, very different. One is a simple chemical reac

    A friend of mine is an excellent chef (mediterranean/mexican fusion with emphasis on seafood), regularly invited to prepare meals in places like Oslo, Paris, London, Evian (Switzerland), San Francisco, Acapulco, etc. No matter what city it is, he splurges on at least one meal at the most celebrated restaurant (according to the gastronomic insiders) in town, and money is no object on these special occasions.

    A couple of years ago, while visiting London, my friend and his wife went to Blumenthal's place, The Fat Duck, specifically for the sampler meal at three hundred pounds per person, for two people. Sixteen tiny courses, fifteen of them with their own specific wine.

    Just to give you an idea, the first course was a sphere chilled to the temperature of liquid nitrogen, handled with chemist's pliers. Within a second of being popped in the mouth, the sphere vaporized and expanded. Containing mostly gas, with some green tea, lemon and vodka, this did three things: cleansed the taste buds, stimulated the appetite and gave an immediate buzz.
    Supposedly, the fourth or fifth course was the proverbial sledgehammer to the head - a quail jelly on a bed of green pea puree and wheat. That's when the sky cracked open and the meaning of life was telepathically revealed from above. After that it was a two-hour haze of "artistic perfection".

    How many of us can say that a certain meal, a sequence of flavor combinations, caused a full-blown epiphany, a mystical experience?

    To this day, my friend's eyes glaze and focus off into infinity while remembering "the best meal I've ever had in my life, the best twelve hundred dollars (!!!) I've ever spent". The good wife agrees, even as the Harrod's shopping budget was obliterated by one dinner.

"How do I love thee? My accumulator overflows."
