Ketchup or catsup is a table condiment with a sweet and sour flavor. The unmodified term ("ketchup") now typically refers to tomato ketchup, although early.
Ketchup recipes began to appear in British and then American cookbooks in the 18th century. The term ketchup first appeared in 1682. In the United States, mushroom ketchup dates back to at least 1770, and was prepared by British colonists in the Thirteen Colonies.
