It is possible, of course, that ketchup is waiting for its own version of that Rolls-Royce commercial, or the discovery of the ketchup equivalent of extra-chunky—the magic formula that will satisfy an unmet need. It is also possible, however, that the rules of Howard Moskowitz, which apply to Grey Poupon and Prego spaghetti sauce and to olive oil and salad dressing and virtually everything else in the supermarket, don’t apply to ketchup.
Tomato ketchup is a nineteenth-century creation—the union of the English tradition of fruit and vegetable sauces and the growing American infatuation with the tomato. But what we know today as ketchup emerged out of a debate that raged in the first years of the last century over benzoate, a preservative widely used in late-nineteenth-century condiments. Harvey Washington Wiley, the chief of the Bureau of Chemistry in the Department of Agriculture from 1883 to 1912, came to believe that benzoates were not safe, and the result was an argument that split the ketchup world in half. On one side was the ketchup establishment, which believed that it was impossible to make ketchup without benzoate and that benzoate was not harmful in the amounts used. On the other side was a renegade band of ketchup manufacturers, who believed that the preservative puzzle could be solved with the application of culinary science. The dominant nineteenth-century ketchups were thin and watery, in part because they were made from unripe tomatoes, which are low in the complex carbohydrates known as pectin, which add body to a sauce. But what if you made ketchup from ripe tomatoes, giving it the density it needed to resist degradation? Nineteenth-century ketchups had a strong tomato taste, with just a light vinegar touch. The renegades argued that by greatly increasing the amount of vinegar, in effect protecting the tomatoes by pickling them, they were making a superior ketchup: safer, purer, and better-tasting. They offered a money-back guarantee in the event of spoilage. They charged more for their product, convinced that the public would pay more for a better ketchup, and they were right. The benzoate ketchups disappeared. The leader of the renegade band was an entrepreneur out of Pittsburgh named Henry J. Heinz.
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 1830’s,” 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. Cortés 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 ketchups also doubled the concentration of sugar—so now ketchup was also sweet—and all along ketchup had been salty and bitter. These are not trivial issues. Give a baby soup, and then soup with MSG (an amino-acid salt that is pure umami), and the baby will go back for the MSG soup every time, the same way a baby will always prefer water with sugar to water alone. Salt and sugar and umami are primal signals about the food we are eating—about how dense it is in calories, for example, or, in the case of umami, about the presence of proteins and amino acids. What Heinz had done was come up with a condiment that pushed all five of these primal buttons. The taste of Heinz’s ketchup began at the tip of the tongue, where our receptors for sweet and salty first appear, moved along the sides, where sour notes seem the strongest, then hit the back of the tongue, for umami and bitter, in one long crescendo. How many things in the supermarket run the sensory spectrum like this?
A number of years ago, the H. J. Heinz Company did an extensive market-research project in which researchers went into people’s homes and watched the way they used ketchup. “I remember sitting in one of those households,” Casey Keller, who was until recently the chief growth officer for Heinz, says. “There was a three-year-old and a six-year-old, and what happened was that the kids asked for ketchup and Mom brought it out. It was a forty-ounce bottle. And the three-year-old went to grab it himself, and Mom intercepted the bottle and said, ‘No, you’re not going to do that.’ She physically took the bottle away and doled out a little dollop. You could see that the whole thing was a bummer.” For Heinz, Keller says, that moment was an epiphany. A typical five-year-old consumes about 60 percent more ketchup than a typical forty-year-old, and the company realized that it needed to put ketchup in a bottle that a toddler could control. “If you are four—and I have a four-year-old—he doesn’t get to choose what he eats for dinner, in most cases,” Keller says. “But the one thing he can control is ketchup. It’s the one part of the food experience that he can customize and personalize.” As a result, Heinz came out with the so-called EZ Squirt bottle, made out of soft plastic with a conical nozzle. In homes where the EZ Squirt is used, ketchup consumption has grown by as much as 12 percent.
There is another lesson in that household scene, though. Small children tend to be neophobic: once they hit two or three, they shrink from new tastes. That makes sense, evolutionarily, because through much of human history that is the age at which children would have first begun to gather and forage for themselves, and those who strayed from what was known and trusted would never have survived. There the three-year-old was, confronted with something strange on his plate—tuna fish, perhaps, or brussels sprouts—and he wanted to alter his food in some way that made the unfamiliar familiar. He wanted to subdue the contents of his plate. And so he turned to ketchup, because, alone among the condiments on the table, ketchup could deliver sweet and sour and salty and bitter and umami, all at once.
Last February, Edgar Chambers IV, who runs the sensory-analysis center at Kansas State University, conducted a joint assessment of World’s Best and Heinz. He has seventeen trained tasters on his staff, and they work for academia and industry, answering the often difficult question of what a given substance tastes like. It is demanding work. Immediately after conducting the ketchup study, Chambers dispatched a team to Bangkok to do an analysis of fruit—bananas, mangoes, rose apples, and sweet tamarind. Others were detailed to soy and kimchi in South Korea, and Chambers’s wife led a delegation to Italy to analyze ice cream.
The ketchup tasting took place over four hours, on two consecutive mornings. Six tasters sat around a large, round table with a lazy Susan in the middle. In front of each panelist were two one-ounce cups, one filled with Heinz ketchup and one filled with World’s Best. They would work along fourteen dimensions of flavor and texture, in accordance with the standard fifteen-point scale used by the food world. The flavor components would be divided two ways: elements picked up by the tongue and elements picked up by the nose. A very ripe peach, for example, tastes sweet but it also smells sweet—which is a very different aspect of sweetness. Vinegar has a sour taste but also a pungency, a vapor that rises up the back of the nose and fills the mouth when you breathe out. To aid in the rating process, the tasters surrounded themselves with little bowls of sweet and sour and salty solutions, and portions of Contadina tomato paste, Hunt’s tomato sauce, and Campbell’s tomato juice, all of which represent different concentrations of tomatoness.
After breaking the ketchup down into its component parts, the testers assessed the critical dimension of “amplitude,” the word sensory experts use to describe flavors that are well blended and balanced, that “bloom” in the mouth. “The difference between high and low amplitude is the difference between my son and a great pianist playing ‘Ode to Joy’ on the piano,” Chambers says. “They are playing the same notes, but they blend better with the great pianist.” Pepperidge Farm shortbread cookies are considered to have high amplitude. So are Hellman’s mayonnaise and Sara Lee poundcake. When something is high in amplitude, all its constituent elements converge into a single gestalt. You can’t isolate the elements of an iconic, high-amplitude flavor like Coca-Cola or Pepsi. But you can with one of those private-label colas that you get in the supermarket. “The thing about Coke and Pepsi is that they are absolutely gorgeous,” Judy Heylmun, a vice president of Sensory Spectrum, Inc., in Chatham, New Jersey, says. “They have beautiful notes—all flavors are in balance. It’s very hard to do that well. Usually, when you taste a store cola it’s”—and here she made a series of
pik! pik! pik!
sounds—“all the notes are kind of spiky, and usually the citrus is the first thing to spike out. And then the cinnamon. Citrus and brown spice notes are top notes and very volatile, as opposed to vanilla, which is very dark and deep. A really cheap store brand will have a big, fat cinnamon note sitting on top of everything.”
Some of the cheaper ketchups are the same way. Ketchup aficionados say that there’s a disquieting unevenness to the tomato notes in Del Monte ketchup: tomatoes vary, in acidity and sweetness and the ratio of solids to liquid, according to the seed variety used, the time of year they are harvested, the soil in which they are grown, and the weather during the growing season. Unless all those variables are tightly controlled, one batch of ketchup can end up too watery and another can be too strong. Or try one of the numerous private-label brands that make up the bottom of the ketchup market and pay attention to the spice mix; you may well find yourself conscious of the clove note or overwhelmed by a hit of garlic. Generic colas and ketchups have what Moskowitz calls a hook—a sensory attribute that you can single out, and ultimately tire of.
The tasting began with a plastic spoon. Upon consideration, it was decided that the analysis would be helped if the ketchups were tasted on French fries, so a batch of fries were cooked up and distributed around the table. Each tester, according to protocol, took the fries one by one, dipped them into the cup—all the way, right to the bottom—bit off the portion covered in ketchup, and then contemplated the evidence of their senses. For Heinz, the critical flavor components—vinegar, salt, tomato ID (overall tomatoness), sweet, and bitter—were judged to be present in roughly equal concentrations, and those elements, in turn, were judged to be well blended. The World’s Best, though, “had a completely different view, a different profile, from the Heinz,” Chambers said. It had a much stronger hit of sweet aromatics—4.0 to 2.5—and outstripped Heinz on tomato ID by a resounding 9 to 5.5. But there was less salt, and no discernible vinegar. “The other comment from the panel was that these elements were really not blended at all,” Chambers went on. “The World’s Best product had really low amplitude.” According to Joyce Buchholz, one of the panelists, when the group judged aftertaste, “it seemed like a certain flavor would hang over longer in the case of World’s Best—that cooked-tomatoey flavor.”
