Ketchup beyond tomatoesSourced
Some historical ketchup was made from mushrooms
British ketchup historically included versions made mainly from mushrooms. A mushroom ketchup recipe also appears in a 1770 manuscript cookbook from English-speaking North America. The familiar name did not always identify a red tomato condiment.
Ketchup had room for an entirely different main ingredient.
