In the U.S., 97 percent of households report having a bottle at the table. How did a simple sauce come to be so loved by America? It turns out ketchup’s origins are anything but American. Ketchup comes from the Hokkien Chinese word, kê-tsiap, the name of a sauce derived from fermented fish. It is believed that traders brought fish sauce from Vietnam to southeastern China.
The first known published tomato ketchup recipe appeared in 1812, written by scientist and horticulturalist, James Mease, who referred to tomatoes as “love apples.” His recipe contained tomato pulp, spices, and brandy but lacked vinegar and sugar.
Americans now purchase 10 billion ounces of ketchup annually, which translates to roughly three bottles per person per year.
