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

What each ingredient does

Tomatoes
Provide the bulk of the butter and its fruity flavor and body as they break down.
Sugar
Adds sweetness and, with long cooking, helps thicken the butter to a spreadable consistency.
Vinegar
Adds acidity that balances the sugar and helps preserve the bright tomato flavor.

The step that matters

Boil slowly for 4 hours. Long, gentle simmering lets water evaporate so the mixture thickens without scorching. Too much heat can burn the sugar and stick to the pan, so stir often and keep the boil slow.

Swap the mace

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

  1. Allspicefits better
  2. Cardamomfits better
  3. Nutmegfits better
  4. Macethe original

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