Ketchup didn't start with Tomatoes

It started off as fermented fish sauce which the Chinese called kê-tsiap, the Malay called it kechap. Americans changed the main ingredient to tomatoes and sold it commercially beginning in 1871. In writings by James Mease, 1812, he referred to the 'love apples' in sauce with spices and brandy instead of vinegar.
