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, moisture and fruity base of the sauce.
Green peppers
Add vegetal flavor and a little texture as they soften during cooking.
Onions
Add savory depth and aroma that builds as they cook down.
Sugar
Adds sweetness that balances the acidity of the vinegar and tomatoes.
Vinegar
Adds acidity that brightens the sauce and sharpens its flavor.
Cinnamon
Adds warm, sweet aroma that gives the sauce its spiced character.

The step that matters

Boil gently, not hard. A sugar-rich sauce can scorch on the bottom of the pot if it boils too vigorously. A gentle simmer lets the liquid reduce evenly and the flavors blend without burning or thickening unevenly over the long cooking time.

Swap the onion

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