A very popular product, tomato sauce,

Interestingly enough, a very popular product, tomato sauce, derives its name from China. Ketchup is a descendant of fish sauces, popular in China, Indonesia and Malaysia today. The consistency of these sauces is about the same as that of tomato sauce. When tomato sauces appeared, their name kecap came into the Dutch language as ketcap, and became ketchup in English. English and Dutch sailors brought the Asian-styled ketchup to Europe. In Chinese ket means tomato, and chup means sauce. Of course, Europeans added many other ingredients to both fish and tomato sauces, such as nuts, vegetables and fruits, but we still have the common name for all tomato sauces - ketchup.
