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

What each ingredient does

Ripe tomatoes
Provide the main body and liquid base of the sauce as they break down when boiled.
Mustard
Adds sharp pungency that gives the sauce its characteristic bite.
Vinegar
Adds acidity that brightens the sauce and helps preserve it.
Red peppers
Contribute heat and sweet, fruity flavor as they simmer with the tomatoes.

The step that matters

Stir in the mustard and vinegar after boiling. Mustard loses its sharp flavor and vinegar's acidity fades when subjected to prolonged heat, so adding them after the long boil keeps the sauce tangy and pungent.
