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 bulk of the sauce as they break down during long simmering.
Brown sugar
Adds sweetness and helps balance the sharpness of the vinegar.
Vinegar
Adds acidity that gives the sauce its tang and helps preserve it.
Red peppers
Contribute savory flavor and a mild heat to the sauce.
Onions
Add savory depth and body as they soften during simmering.

The step that matters

Boil gently for 3 hours, stirring frequently. Long, gentle simmering thickens the sauce by evaporating water and concentrates flavors. Frequent stirring prevents sugars and solids on the bottom of the pan from scorching, which would cause a burnt taste.

Swap the onion
