Ketchup (also spelled catsup or catchup), also known as tomato ketchup, tomato sauce, red sauce, Tommy sauce, Tommy K, or dead horse, is a condiment, usually made from tomatoes. The ingredients in a typical modern ketchup are tomato concentrate, spirit vinegar, corn syrup or other sugar, salt, spice and herb extracts (including celery), spice and garlic powder. Allspice, cloves, cinnamon, onion, and other vegetables may be included.

Ketchup started out as a general term for sauce, typically made of mushrooms or fish brine with herbs and spices. Some popular early main ingredients included blueberry, anchovy, oyster, lobster, walnut, kidney bean, cucumber, cranberry, lemon, celery and grape. Mushroom ketchup is still available in some countries, such as the UK, and banana ketchup is popular in the Philippines.

Ketchup is often used with chips (French fries), hamburgers, sandwiches and grilled or fried meat. Ketchup with mayonnaise forms the base of Thousand Island dressing and fry sauce. Ketchup is also typically used as a base for barbecue sauce.

History

Origins

Tomato ketchup

By 1801 a recipe for tomato ketchup was printed in an American cookbook, the Sugar House Book. James Mease published another recipe in 1812. In 1824 a ketchup recipe appeared in The Virginia Housewife, an influential 19th-century cookbook written by Mary Randolph, Thomas Jefferson's cousin.

As the century progressed, tomato ketchup began its ascent in popularity in the United States, influenced by the American enthusiasm for tomatoes. Tomato ketchup was sold locally by farmers. A man named Jonas Yerks (or Yerkes) is believed to have been the first man to make tomato ketchup a national phenomenon. By 1837 he had produced and distributed the condiment nationally. Shortly thereafter, other companies followed suit. F. & J. Heinz launched their tomato ketchup in 1876. Heinz tomato ketchup was advertised: "Blessed relief for Mother and the other women in the household!"

The Webster's Dictionary of 1913 defined "catchup" as a "table sauce made from mushrooms, tomatoes, walnuts, etc. also ketchup."

Modern ketchup emerged in the early years of the 20th century, out of a debate over the use of sodium benzoate as a preservative in condiments. Harvey W. Wiley, the "father" of the Food and Drug Administration in the U.S., challenged the safety of benzoate. In response, entrepreneurs, particularly Henry J. Heinz, pursued an alternative recipe that eliminated the need for that preservative.
