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

What each ingredient does

Tomatoes
Provide the main body and moisture that the sauce is built on.
Vinegar
Adds acidity that gives the sauce its tang and helps preserve it.
Sugar
Balances the acidity and adds sweetness to the sauce.
Peppers
Contribute bulk, flavor, and some heat to the sauce.

The step that matters

Boiling for two hours. Long simmering evaporates water and softens the vegetables, thickening the sauce and concentrating its flavor. Stopping early leaves it thin and watery.

Swap the tomato

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

  1. Capsicumfits better
  2. Mustardfits better
  3. Sweet potatofits better
  4. Tomatothe original

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