Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Ripe tomatoes
Provide the main body and moisture that cook down into the butter.
Brown sugar
Adds sweetness and helps thicken the butter as it cooks down.
Vinegar
Adds acidity that balances the sweetness and brightens the flavor.

The step that matters

Boil the mixture until thickened. Sugar and tomato pulp must reduce long enough to reach a spreadable thickness. Stopping too early leaves a thin, runny butter that may spoil sooner, while overcooking can scorch the sugar.

Swap the tomato

How well each one fits the dish's main ingredients (sugar, vinegar, cinnamon, clove, allspice):

  1. Mustardfits better
  2. Horseradishfits better
  3. Capsicumfits better
  4. Tomatothe original

Fit is the average pairing score against sugar, vinegar, cinnamon, clove, allspice. Candidates are from the same food group and used in at least 100 recipes.
