Ketchup

Origin: United States (modern tomato form); ultimate etymological roots in Chinese/Malay fermented fish and soy sauces. A smooth, sweet-tangy tomato sauce of tomatoes, vinegar, sugar, and spices, standardized into its familiar modern form largely by American manufacturers in the late 19th and early 20th centuries.

Flavor Profile: Sweet, tangy, and mildly spiced, with tomato’s natural umami rounded out by significant added sugar.

Culinary Uses: Nearly universal condiment for fries, burgers, and hot dogs across American food culture; ingredient in sauces (cocktail sauce, some barbecue sauces).

Regional Variations: Regional and international variants exist (curry ketchup in Germany, banana ketchup in the Philippines); “tomato sauce” in Australia and “catsup” as an older American spelling both refer to essentially the same product.

Storage: Keeps many months unopened; refrigerate after opening, though the vinegar and sugar content means it stays safe for a long time even unrefrigerated.

Notes: The word itself traces through Hokkien “kê-tsiap” and Malay “kecap” even though the modern tomato-based product bears no resemblance to those ancestral condiments.
