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

What each ingredient does

Tomatoes (in the method)
Break down into the body of the sauce, adding moisture and a fresh, sharp flavour.
Onions
Add sweetness and savoury depth as they soften during the long cook.
Green peppers
Contribute a grassy, slightly bitter note and body to the sauce.
Vinegar
Adds acidity that sharpens the flavour and helps preserve the sauce.
Brown sugar
Balances the acidity with sweetness and adds a deeper, caramel-like flavour.

The step that matters

Cook slowly for 2 to 3 hours, stirring frequently. Gentle, prolonged simmering lets the vegetables break down and the liquid reduce into a thick sauce. Heating too fast or leaving it unstirred can scorch the sugars and sticks on the bottom of the pot.

Swap the onion

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