One English condiment is named for Chinese fermented fish sauce

The Chinese Origins of a Borrowed Name

In the bustling ports of Fujian Province during the seventeenth century, Chinese traders sold a pungent condiment called 'kê-tsiap'—a fermented brine made from fish guts, soybeans, and salt. British sailors tasted it, loved the umami punch, and carried the word home, though not the recipe. By the 1690s, English cookbooks featured 'katchup' and 'catsup' recipes using anchovies, mushrooms, walnuts, and oysters—anything fermented and salty. The tomato, a New World fruit only recently accepted in European kitchens, didn't appear in ketchup until the early 1800s. When Heinz bottled his tomato version in 1876, he kept the old Hokkien name, and it became the English-speaking world's default condiment label.

The mismatch between name and ingredient reflects a linguistic quirk: English borrowed the word for one thing and applied it to another. In Hokkien, 'kê' referred to fermented seafood and 'tsiap' meant sauce. British cooks heard the sound, transliterated it a dozen ways—'ketsup', 'catchup', 'catsoup'—and used it to describe any spiced, shelf-stable sauce. By 1800, American recipes listed more than a hundred 'ketchups', from grape to lemon to cucumber. The tomato variant won out because tomatoes were cheap, abundant, and tolerated the sugar and vinegar that made mass production viable. Heinz's 1876 formula used ripe tomatoes, not green ones, which cut the bitterness and let him reduce preservatives, giving his product a sweeter, brighter taste that dominated the market.

How a Fish Sauce Became a Tomato Empire

Heinz didn't invent tomato ketchup—dozens of American manufacturers sold it by the 1870s—but he did make it a household staple. His glass bottles, narrow necks, and octagonal shape signaled purity at a time when competitors added coal-tar dyes and sodium benzoate. Heinz lobbied Congress to pass the 1906 Pure Food and Drug Act, turning transparency into a competitive advantage. His factory in Pittsburgh processed three million bottles a year by 1900, and his marketing slogan—'57 Varieties'—became shorthand for American abundance, even though he offered more than sixty products. The number stuck because Heinz liked how it looked on billboards. By 1905, Heinz ketchup outsold every rival, and 'ketchup' became synonymous with the tomato-and-vinegar blend, erasing the mushroom and walnut recipes from popular memory.

The Chinese origins of the word stayed hidden for generations. Most English speakers assumed 'ketchup' was an English coinage or a borrowing from French. Linguists didn't trace it definitively to 'kê-tsiap' until the twentieth century, when scholars compared British East India Company trade records with Hokkien dictionaries. The word had traveled from Fujian to Batavia, from Batavia to London, and from London to Pittsburgh, changing its referent at every stop. Today, Americans consume roughly three bottles of Heinz ketchup per household per year, and almost none know they're saying 'fermented fish sauce' every time they ask someone to pass the ketchup. The disconnect between sound and substance reveals how global trade reshapes language faster than it reshapes recipes.

The Unexpected Power of a Misnamed Condiment

Ketchup's linguistic fossil tells us something about cultural borrowing: we keep the names even when we abandon the things. English is full of these orphaned words—'salary' from Roman salt rations, 'mortgage' from Norman death pledges, 'disaster' from Latin bad stars. 'Ketchup' is unusual because the original product still exists. In Southeast Asia, fish-based kê-tsiap descendants like Thai nam pla and Vietnamese nuoc mam remain kitchen staples, and in the Philippines, a tomato-free banana ketchup dominates tables. The word split into parallel meanings, each culture preserving a different evolutionary branch. English speakers inherited the Hokkien label and retrofitted it onto a tomato paste, while Hokkien speakers kept using the word for its original referent. The result is a rare case of a loanword that means opposite things in its source and target languages.

The staying power of 'ketchup' also demonstrates brand dominance. Heinz's 1876 trademark locked in one spelling—'ketchup' over 'catsup' or 'catchup'—and one flavor profile, marginalizing every competitor. By the 1980s, Heinz controlled 60 percent of the U.S. market, and 'ketchup' had become generic, like 'kleenex' or 'xerox'. The word's Chinese roots survived because they were invisible; if Heinz had called his product 'tomato sauce', the Hokkien etymology would have vanished entirely. Instead, every bottle on every diner table carries a fragment of seventeenth-century Fujian, a reminder that global trade doesn't just move goods—it rewires language, one fermented fish sauce at a time.
