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

What each ingredient does

Tomatoes
Provide the bulk and body of the sauce as they break down during long simmering.
Vinegar
Adds acidity that sharpens flavour and helps preserve the finished sauce.
Sugar
Adds sweetness that balances the acidity and helps thicken the sauce as water evaporates.

The step that matters

Simmer for 3 hours, stirring occasionally. A long, gentle simmer lets water evaporate and the sauce thicken. Stirring prevents sugars and solids from scorching on the bottom of the pot.

Swap the tomato

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

  1. Horseradishfits better
  2. Capsicumfits better
  3. Shallotfits better
