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 break down into a thick, moist base.
Brown sugar
Adds sweetness and helps thicken the sauce as it reduces.
Vinegar
Adds acidity that sharpens the flavor and helps preserve the sauce.
White mustard seed
Contributes pungent flavor that mellows during long simmering.

The step that matters

Adding the vinegar and simmering. Vinegar is added only after the vegetables have cooked down, so its acidity is not diluted by early liquid. Extended boiling then concentrates the sauce and thickens it, which is essential for a stable, shelf-ready result.

Swap the onion

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

  1. Capsicumfits better
  2. Horseradishfits better
  3. Sweet potatofits better
  4. Onionthe original

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