Proving It

Originally Published January 2005
Taking kitchen science to a whole new (molecular) level, Hervé This is changing the way France—and the world—cooks.

Charging up the rue François 1er to an interview at Radio France, the man who is trying to change French gastronomy is talking egg whites, discussing their viscosity, their surface tension, and different ways of introducing air into them. One is the whisk; another is the bicycle pump. He is not seriously proposing the use of cycling equipment to make a soufflé, but, multiplying the diameter of a whisk wire by the number of wires in the whisk by the average depth of each whisking movement, he concludes that the standard whisk is little better than medieval, and begins to speculate about better options.

Hervé This is not a cook, but a scientist. He does not work in the oven-blasted heat of kitchens, but in the thin, rarefied air of the Collège de France. He doesn’t grow misty-eyed over Fernand Point, the legendary cook who first mined the regional vein in haute cuisine; he grows emotional over Antoine Lavoisier, the 18th-century researcher who drew chemistry out of the alchemical night. By dint of his energy and intellect, This (pronounced “Tees”) has become the leader of a discipline called molecular gastronomy. It is his conviction that forcing the canons of the French table through the sieve of hard science will create a new form of cooking from which the dust of centuries will have been loosened and all useless procedures discarded. Armed with an IBM ThinkPad and a bone-handled Laguiole penknife, he applies himself to the task daily and passionately, in the role of showman and savant.

Headquarters for the campaign is the Collège de France, a stately building with a cobbled courtyard that stands across the Rue St.-Jacques from the back entrance of the Sorbonne. To give an American approximation of the intellectual weight that the institution carries, one would have to multiply Yale, Harvard, and MIT several times over and roll them into one. Despite its pedigree, the atmosphere is marked as much by modesty as by erudition. Since the founding of the Collège, Parisians have been able to simply walk in off the street and attend lectures. Today, skateboarding teenagers might be found launching themselves from the base of a statue of Claude Bernard (author of a 19th-century landmark study on experimental medicine) that stands in front of the building. The massive, unmarked vine that crawls up a courtyard wall is one of the first ever to be grafted onto American rootstock, a technique that saved the French wine industry from phylloxera in the late 19th century.

This’s small fourth-floor office in this august institution, reached by a rickety elevator and a walk down a cluttered corridor, is nothing if not humble. The visitor who expects to push open the door and find This pacing between assistants shouting, “I want a meeting with the fricassee team,” or asking how the papers on profiteroles are coming along is in for a surprise. On the cluttered desk, The Merck Index leans against Escoffier’s Guide Culinaire; on the floor, household pots are stacked against a centrifuge. It is unclear whether the labeled beakers and petri dishes that take up the counters are experiments currently being observed, recently concluded, or long since forgotten. The room is not so much a laboratory as an extension of This’s mind.

One would describe This as tall if he didn’t always seem crouched, about to pounce on an imprecision. One would never describe him as calm. Brushing his lank gray hair from his eyes, wearing his signature white collarless shirts, and invariably in motion, he has the demeanor of a country vicar delivering a particularly impassioned sermon. His face has two basic settings. Look one, wide-eyed and charmed, seems always to be saying, “See, science isn’t that hard at all!” Look two is more tentative, gauging just how much hard science a particular audience can deal with. It must be said that he is good-looking, but he is much more than just a handsome academic. He is a public intellectual, which in France means he is a star.

The field of molecular gastronomy began over a meal that This shared with a retired Anglo-Hungarian physicist named Nicholas Kurti in 1985. At the time, This was editing the popular science journal Pour la Science while doing culinary experiments at home. An advertising rep told him about Kurti, who was doing the same in his Oxford laboratory. Within days, the two men were sharing a poulet au vin jaune at Chez Maître Paul.

Kurti died in 1998, but This is clearly devoted to the man—he can list his idol’s career from a Budapest Gymnasium to the Legion of Honor like a San Francisco Giants fan reeling off Willie McCovey’s batting average. Other stars in the world of culinary science were similarly taken with Kurti. Endearingly, the word Champagne comes up with great frequency when his name is mentioned. Harold McGee, who published the groundbreaking On Food and Cooking in 1984, recalls planning the first conference of molecular gastronomy over a half-finished bottle that Kurti brought out in the shabby Berkeley, California, motel where he was staying. Shirley Corriher, the best-selling author of CookWise, recalls that chilled Moët & Chandon was served promptly at 11:30 after the morning seminars at that first conference.

A central question about molecular gastronomy seems to rise from these lovely details, for the world of Champagne receptions is not the world of kitchens. Few outside the profession truly understand the physical demands on a cook or understand the stress level induced by being judged on every single dish you put out during the rush of a service twice every day. Where does molecular gastronomy fit in? Is it a discipline that can actually help chefs put out good food and meet payroll? Or does it simply provide modern scientific tools for that age-old need of some chefs to serve an ingredient in a form different than its own? Before, we’d be presented with fish mousse in the shape of the Arc de Triomphe; today’s fashionable cooking can seem to be all about emulsions, gels, and foams.

This himself can make it sound like the most impractical of disciplines. He talks of the “paradox of the velouté,” has published charts on the different rates at which coffee chills depending on when one adds milk, and once spent more than three months researching whether egg whites should be stiff or soft for a soufflé. His talk can reach such a point of theoretical abstraction that an inner heckler can be heard to say, “Sorry, pal, there’s no final frontier in my fridge.”

Yet a moment later he can seem like the only person in the French food world who is facing facts. For French food today is indeed caught in a vise, between the unchanging expectations of the clientele and the reduced ability of chefs to meet them. The 35-hour workweek (and the five-week vacation and towering labor costs that trail after it) has introduced a hard concrete figure in among the sepia tones of the French culinary heritage. Every restaurant shows signs of the struggle it entails. At the little corner bistro, you might notice there is not a single vegetable garnish because the patron simply can’t afford a second employee (he’s already cooking appetizers, main courses, and desserts, and he and his wife will wash the dishes when everyone leaves). At the Michelin three-star, they don’t stint on employees—and a soufflé for one costs 40 euros. That is close to $50 for dessert.

What is it behind these figures that risks getting lost? Is French food to become a choice between cut corners and shored-up grandeur at exorbitant prices? It hardly even strikes one as alarmist to say that a certain idea of France is at stake. No country has its identity so entwined with its food. For the French, as for many of us, the rustic calm of poplar-lined country roads can be evoked by the caramelized edges of a tarte aux fruits, the serene permanence of its traditions captured in the braised lettuce and pearl onions mixed in with a buttery serving of petits pois à la française. If we lose French food, we will have lost France.

It is because the question crystallizes around the figure 35—the hours in that workweek—that This returns to it time and again. It is his touchstone, the number that gives weight to his theories and purpose to his actions. The experiments he is proudest of are those that disprove a traditional technique and would, if implemented, shear precious minutes from the labors of cooking. The paradox of the velouté, for example, is in fact just that. Traditionally, it has been maintained that the foam rising to the surface of a flour-thickened sauce is an impurity. However, This has made clinically sterile veloutés from which the foam still rises. Such a discovery might sound inconsequential, but it certainly is not to the kitchen apprentice who has to spend the break between lunch and dinner doing the skimming.

The crisis in French gastronomy represents the moment that a scientific approach to cooking has been waiting for, and This has grabbed it with both hands. The paradox of this grandee of the Collège de France is that he spends his time thinking of ways to save time for kitchen workers he will never meet. His whole life revolves around diffusing the message that French cooking can be saved through the enlightening principles of molecular gastronomy. A father of two, he doesn’t own a television or read newspapers. On any given day of the week, there are constant appointments to be made, performances taped, lectures delivered, and best sellers promoted. (The first English translation of one of his books, Casseroles and Éprouvettes: Pots, Pans, and Test Tubes, will be published by Columbia University Press this fall.)

His friend Pierre Gagnaire, the Michelin three-star chef with whom This collaborates on recipes (accessed at pierre-gagnaire.com), says of This, “He must impose himself on every level of French gastronomy. He’d go to dinner at the Confrérie de l’Andouillete,” which is akin to going to the opening of an envelope. He also pays This the highest compliment one civilized Frenchman can pay another. “He makes us want to think.”

A recent talk brought This to the Université de Paris-Sud at Orsay, a boxy, aging campus located in the hinterland where the outermost reaches of the Paris suburbs finally bleed back into the fields and forests of the Île-de-France. The setting was a world away from the Collège de France, and yet This, as always, seemed totally at ease, oblivious of his environment, fiercely intent on the exchange.

“Pretend I’m a Martian and I want to make puff pastry,” he started. The nine chemistry undergraduates gathered around him laughed. They expected such a launching point from a man many had only seen before on television. The blazer was off, his strength apparent under the fabric of his shirt, his intensity palpable every time he leaned forward to cajole an answer from a shy undergraduate. Behind him on the tiled counter, his ever-present laptop swirled on screen saver mode; beside it lay the unusual mix of a bag of flour, a bottle of vegetable oil, a russet potato, and Pyrex beakers and test tubes. In this setting, This appeared like a man positioned between tradition and modernity, a man who embodied the twin heritages that are his, that of a Frenchman and that of a scientist, who by his indefatigable energy reassures the French that their cooking will remain eternal even as it wrestles with the challenges of the everyday.

But at that moment he was a Martian who wanted to make puff pastry. First he had to find out whether starch is heavier than water. He cut the potato in half with his penknife, crosshatched the inside surface, and dunked the potato in a beaker of water. A white film started to descend through the water. The students commented on the simplicity of the proof. This smiled. He had the audience. He flashed look one.
