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

What each ingredient does

Tomatoes
Provide the bulk of the sauce and its body, softening into a thick, moist base as they boil.
Mustard
Adds sharp, pungent flavour that gives the sauce its characteristic bite.
Vinegar
Adds acidity that brightens the sauce and balances the rich, spiced flavours.
Onions
Add savoury depth and sweetness that builds as they cook down into the sauce.

The step that matters

Adding the mustard and vinegar after cooling. Mustard's sharp pungency and vinegar's bright acidity are volatile and easily dulled by prolonged heat. Stirring them in once the sauce has cooled helps keep their flavour sharp.
