Glossary of food terms: K

Ketchup

Often called catsup in the US, this thick, slightly sweet and spicy sauce is a traditional American accompaniment for French fries, hamburgers and many other foods. It's usually made from tomatoes, vinegar, sugar and spices, but other flavours such as mushroom ketchup or various fruit ketchups are available.

It's sold in glass or plastic squeezy bottles and, as well as being used as a condiment, can be an ingredient in its own right - in homemade barbecue sauce, for example.
