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

What each ingredient does

Tomatoes
Form the bulk of the sauce and provide its main body and moisture.
Vinegar
Adds acidity that gives the sauce its tang and helps preserve it.
Brown sugar
Adds sweetness that balances the acidity and spice.
Horseradish
Contributes a sharp, pungent bite to the sauce.
Onion
Adds savory depth and body as it softens during cooking.
Red peppers
Add sweetness, colour and a mild heat to the sauce.

The step that matters

Simmer until well combined and heated through. Simmering long enough lets the raw vegetables soften and the spices and acid blend into one sauce. Stopping early can leave it harsh and uneven, while the sauce thickens as moisture evaporates.

Swap the tomato

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

  1. Shallotfits better
  2. Radishfits better

  4. Tomatothe original

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