Ketchup

Ketchup is a purée made from sun-ripened tomatoes. Many households in the Western world have a bottle of ketchup in the kitchen, where it is one of the most frequently used umami enhancers. Although ketchup is often associated with American fast food, such as hamburgers and fries, its roots are actually to be found in the Far East and Indonesia, where it was first fermented as a special type of salty, spicy fish sauce. The origin of the name is unknown, but a variant of it is the name of the original Chinese fish sauce, koe-chiap, which refers to the brine in which fish and shellfish were marinated in China.
