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 flavor.
Vinegar
Adds acidity that gives the sauce its tang and helps preserve it.
Sugar
Balances the acidity and vinegar with sweetness and helps thicken the sauce as it cooks.
Onions
Add savory depth and body as they soften during cooking.

The step that matters

Cook the mixture over medium heat for 1 hour, stirring occasionally. Slow cooking reduces the water in the tomatoes and thickens the sauce. Stirring prevents the sugar and tomato solids from scorching on the bottom of the pot.

Swap the onion

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

  1. Capsicumfits better
  2. Mustardfits better
  3. Cucumberfits better
  4. Onionthe original

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