It is thought that British explorers brought back Kê-tsiap or kĕchap, a brine of pickled fish or shell-fish, from China and the Malay states in the 18th century and called it Catchup or Catsup. As the Brits have often done with foods from other cultures, we experimented and adapted it to suit our cuisine so there were recipes for cucumber, mushroom or walnut catchup. It wasn’t until a hundred years later that the Americans began to make tomato catsup or ketchup and it began to resemble the tomato ketchup we know today. Oysters and anchovies were cheap in the 19th century and I particularly like this recipe for oyster catchup which requires large quantities!
If you’re feeling brave, why not have a go? It might make an excellent condiment for a dinner party!
