History of ketchup is one of the funniest stories of cooking. The earliest generation of ketchup did not contain tomato at all and English people made it based on Chinese cooking. Main ingredients of the first generation of ketchup included: types of fish, mushroom and vegetables such as eggplant. However, ketchup in its current original tomato-flavored form was first devised in 1905 by a person named Henry J,Heinz who added vinegar- used to be applied for long-term preservation- to extend the shelf life without adding any harmful preservatives.
