Key concepts

3 concepts

  1. 1

    Early ketchups were unlike the tomato-based condiment we know today; they were often sweet and savory brown sauces that didn't even contain tomatoes.

  2. 2

    The origin of ketchup can be traced back to fish sauce, a condiment used in ancient China, Greece, and Rome for its rich, umami flavor.

  3. 3

    James Mease, a Philadelphian physician, introduced the first tomato-based ketchup in 1812, and Henry J. Heinz later refined the recipe by using riper tomatoes and vinegar, creating the thick, goopy formula popular today.
