What was ketchup first made of?

Nearly everyone likes ketchup, and even one ice cream manufacturer to make an ice-cream with ketchup flavor. Ketchup has got other names too – tomato sauce, red sauce, Tommy sauce. But not everyone knows that first ketchups weren’t made from tomatoes. When ketchup was originally developed by the Chinese in 1690, it contained no tomatoes. It was made out of pickled fish, shellfish, mushrooms 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.
