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

What each ingredient does

Tomatoes
Provide the main bulk and liquid that reduces into the thick sauce body.
Green peppers
Add vegetable flavor and a slightly firm texture to the sauce.
Granulated sugar
Adds sweetness that balances the sharpness of the vinegar and tomatoes.
Vinegar
Adds acidity that brightens the flavor and helps preserve the sauce.

The step that matters

Cook slowly and stir occasionally. As liquid evaporates over two hours, the sugar and solids concentrate and can scorch on the bottom of the pot. Regular stirring and gentle heat keep the sauce from burning and sticking while it thickens.

Swap the tomato

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

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

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