One of the earliest records of ketchup is a 1732 English recipe entitled “Ketchup in Paste, From Bencoulin in the East Indies” (modern day Indonesia). Doctors in other parts of the U.S. started to prescribe tomatoes to cure indigestion and diarrhea. Tomato ketchup had finally been born. Salsa now outsells ketchup by dollar amount, says Tebben, yet American households still purchase more tomato ketchup by volume. Two centuries after its medical rebranding, ketchup has yet to be dethroned as king of American condiments.
