The shift to modern ketchup started in the United States. In 1812, James Mease created the first tomato-based recipe. Interestingly, H.J. Heinz began selling “Tomato Catsup” in 1876, using that spelling to distinguish their product in a crowded market. As commercial production grew, Henry J. Heinz, with his 1876 product, relied on chemical preservatives such as formalin (aka formaldehyde, uh gross!) and coal tar to maintain color and freshness..
Worcestershire sauce is another modern, Western relative of kê-tsiap. Both derive profound umami from fermented fish (anchovies) and aging, offering a similar pungent, savory profile. Developed in Britain, it was inspired by the savory umami profile of Asian fish sauce.
