The World's First Ketchup Didn't Start With Tomatoes

How Did Fish Sauce Become Tomato Ketchup?

Long before tomato ketchup became a staple on American tables, people in Southeast Asia and China were using a fermented fish sauce as the original version of this condiment. This early sauce, made from salted fish and spices, dates back centuries and spread through trade routes to Europe, where it evolved over time into the tomato-based version familiar today.

The origins of ketchup trace back to a briny, fermented fish sauce known as ke-tsiapin the Hokkien language, used primarily as a seasoning for fish and rice. British traders encountered it in the 17th century and brought samples back to Europe, where they attempted to recreate it using ingredients like mushrooms, walnuts, and anchovies. Tomatoes were not part of the recipe until the 19th century, when they became widely available and accepted in Western cooking.

What Role Did Trade and Taste Play in the Change?

Early European versions of ketchup were thin, dark sauces meant to add umami flavor to meats and stews. As tomatoes gained popularity in the United States, cooks began experimenting with them as a base, combining the fruit with vinegar, sugar, and spices. The result was a thicker, sweeter sauce that appealed to American tastes. By the mid-1800s, tomato ketchup was being mass-produced, and companies like Heinz helped standardize the recipe and packaging.

Global trade brought new ingredients and ideas to Europe, encouraging culinary experimentation. The shift from fish-based to tomato-based ketchup reflected changing palates and the growing influence of American cuisine. Tomatoes, once viewed with suspicion, became a symbol of freshness and innovation. The adaptation also allowed for longer shelf life and easier mass production, which suited industrial food manufacturing.

What was the original ingredient in ketchup? The original ketchup was a fermented fish sauce made from salted fish and spices, originating in Southeast Asia.
