Ketchup

Ketchup (/ˈkɛtʃəp/ or /ˈkɛtʃʌp/), or catsup, is a table sauce. Traditionally, different recipes featured ketchup made of egg white, mushrooms, oysters, mussels, walnuts, or other foods, but in modern times the term without modification usually refers to tomato ketchup, often called tomato sauce or red sauce (in Northern Ireland). It is a sweet and tangy sauce, typically made from tomatoes, a sweetener, vinegar, and assorted seasonings and spices. Seasonings vary by recipe, but commonly include onions, allspice, cloves, cinnamon, garlic, and sometimes celery. Heinz tomato ketchup, which contains 23.7 g sugar and 3.1 g of salt per 100 g, is the market leader, with an 82% market share in the UK.

Tomato ketchup is often used as a condiment with various dishes that are usually served hot, including chips/fries, hamburgers, sandwiches, hot dogs, french toast, eggs, and grilled or fried meat. Ketchup is sometimes used as a basis or ingredient for other sauces and dressings. Ketchup is also used as a flavoring for things such as potato chips, and this variety of chips is one of the most popular flavors in Canada. This flavor of potato chip has also been offered in the U.S. as recently as September 2014.
