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 body and acidity.
Mustard
Adds sharp pungency that gives the sauce its characteristic bite.
Red peppers
Contribute sweetness and flavour to the base as they cook down.
Vinegar
Adds acidity that sharpens flavour and helps preserve the sauce.
Onions
Add savoury depth and body as they soften during the long boil.

The step that matters

Stir in the mustard and vinegar after cooling. Mustard's pungent compounds fade and turn harsh or bitter when heated for long, and vinegar's sharpness dulls under prolonged cooking. Adding them after the sauce has cooled keeps their bite and flavour fresh.
