What the Dog Saw [19]
The world’s leading expert on ketchup’s early years is Andrew F. Smith, a substantial man, well over six feet, with a graying mustache and short wavy black hair. Smith is a scholar, trained as a political scientist, intent on bringing rigor to the world of food. When we met for lunch not long ago at the restaurant Savoy in SoHo (chosen because of the excellence of its hamburger and French fries, and because Savoy makes its own ketchup — a dark, peppery, and viscous variety served in a white porcelain saucer), Smith was in the throes of examining the origins of the croissant for the upcoming Oxford Encyclopedia of Food and Drink in America, of which he is the editor-in-chief. Was the croissant invented in 1683, by the Viennese, in celebration of their defeat of the invading Turks? Or in 1686, by the residents of Budapest, to celebrate their defeat of the Turks? Both explanations would explain its distinctive crescent shape — since it would make a certain cultural sense (particularly for the Viennese) to consecrate their battlefield triumphs in the form of pastry. But the only reference Smith could find to either story was in the Larousse Gastronomique of 1938. “It just doesn’t check out,” he said, shaking his head wearily.
Smith’s specialty is the tomato, however, and over the course of many scholarly articles and books — “The History of Home-Made Anglo-American Tomato Ketchup,” for Petits Propos Culinaires, for example, and “The Great Tomato Pill War of the 1830s,” for The Connecticut Historical Society Bulletin — Smith has argued that some critical portion of the history of culinary civilization could be told through this fruit. Cortez brought tomatoes to Europe from the New World, and they inexorably insinuated themselves into the world’s cuisines. The Italians substituted the tomato for eggplant. In northern India, it went into curries and chutneys. “The biggest tomato producer in the world today?” Smith paused, for dramatic effect. “China. You don’t think of tomato being a part of Chinese cuisine, and it wasn’t ten years ago. But it is now.” Smith dipped one of my French fries into the homemade sauce. “It has that raw taste,” he said, with a look of intense concentration. “It’s fresh ketchup. You can taste the tomato.” Ketchup was, to his mind, the most nearly perfect of all the tomato’s manifestations. It was inexpensive, which meant that it had a firm lock on the mass market, and it was a condiment, not an ingredient, which meant that it could be applied at the discretion of the food eater, not the food preparer. “There’s a quote from Elizabeth Rozin I’ve always loved,” he said. Rozin is the food theorist who wrote the essay “Ketchup and the Collective Unconscious,” and Smith used her conclusion as the epigraph of his ketchup book: ketchup may well be “the only true culinary expression of the melting pot, and… its special and unprecedented ability to provide something for everyone makes it the Esperanto of cuisine.” Here is where Henry Heinz and the benzoate battle were so important: in defeating the condiment Old Guard, he was the one who changed the flavor of ketchup in a way that made it universal.

There are five known fundamental tastes in the human palate: salty, sweet, sour, bitter, and umami. Umami is the proteiny, full-bodied taste of chicken soup, or cured meat, or fish stock, or aged cheese, or mother’s milk, or soy sauce, or mushrooms, or seaweed, or cooked tomato. “Umami adds body,” Gary Beauchamp, who heads the Monell Chemical Senses Center, in Philadelphia, says. “If you add it to a soup, it makes the soup seem like it’s thicker — it gives it sensory heft. It turns a soup from salt water into a food.” When Heinz moved to ripe tomatoes and increased the percentage of tomato solids, he made ketchup, first and foremost, a potent source of umami. Then he dramatically increased the concentration of vinegar, so that his ketchup had twice the acidity of most other ketchups; now ketchup was sour, another of the fundamental tastes. The post-benzoate
