The Origin of Ketchup and Mustard
Ketchup and mustard have long histories. However, neither condiment started in exactly the form we see in supermarkets today.
History of Ketchup
The history of ketchup goes back much further than modern tomato sauce.
The word is commonly linked to the Hokkien Chinese term kê-tsiap, which referred to a fermented fish sauce. Traders carried similar sauces through Southeast Asia, and European traders later brought the idea to Europe.
Early European ketchup recipes often used ingredients such as:
- Mushrooms
- Walnuts
- Anchovies
- Oysters
- Spices
Tomatoes became part of ketchup recipes in the United States during the early 19th century. James Mease published an early tomato ketchup recipe in 1812.
Over time, vinegar, sugar, and other ingredients helped create the thick, sweet, and tangy tomato ketchup familiar today.
History of Mustard
Mustard has been used as a food ingredient for thousands of years. Ancient communities valued mustard seeds for their strong flavor.
The Romans helped develop prepared mustard by combining crushed mustard seeds with grape must, which is freshly pressed grape juice. The Latin expression mustum ardens, meaning “burning must,” is associated with the origin of the word mustard.
Mustard later spread throughout Europe. It became especially popular in France, Germany, and England.
Today, mustard is available in several forms, including yellow mustard, Dijon mustard, whole-grain mustard, and spicy brown mustard.
