When Jim Wigon set up shop that day in Zabar’s, then, his operating assumption was that there ought to be some segment of the population that preferred a ketchup made with Stanislaus tomato paste and hand-chopped basil and maple syrup. That’s the Moskowitz theory. But there is theory and there is practice. By the end of that long day, Wigon had sold ninety jars. But he’d also got two parking tickets and had to pay for a hotel room, so he wasn’t going home with money in his pocket. For the year, Wigon estimates, he’ll sell fifty thousand jars—which, in the universe of condiments, is no more than a blip. “I haven’t drawn a paycheck in five years,” Wigon said as he impaled another meatball on a toothpick. “My wife is killing me.” And it isn’t just World’s Best that is struggling. In the gourmet-ketchup world, there is River Run and Uncle Dave’s, from Vermont, and Muir Glen Organic and Mrs. Tomato Head Roasted Garlic Peppercorn Catsup, in California, and dozens of others—and every year Heinz’s overwhelming share of the ketchup market just grows.

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 wearil
