Why is ketchup also called catsup?
Despite them now being synonymous with ketchup, Heinz was one of the later companies to produce this product which is why they changed the name of their product from ‘catsup‘ to ‘ketchup‘. So, catsup is just another word to describe ketchup, and it is likely derived from the Chinese word ‘ke-tsiap’ for fish sauce.
When did catsup change to ketchup?
The H. J. Heinz Company, a name that’s synonymous with ketchup for most people today, was a relative latecomer to the game and didn’t produce a tomato-based ketchup until 1876. They originally referred to their product as catsup, but switched to ketchup in the 1880s to stand out.
Where do they say catsup?
Some sources say that the British found ketsaip in China (which became “catsup“) and the Dutch found kecap in Malaysia (which became “ketchup”). Others say that different Brits found kôe-chiap and kê-chiap in China, and that’s how we ended up with two different words for the same thing.
