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

What each ingredient does

Green tomatoes
Provide the main body and tart flavour of the sauce as they cook down.
Sugar
Adds sweetness that balances the sharpness of the vinegar and green tomatoes.
Vinegar
Supplies acidity that gives the sauce its tang and helps preserve it.
Black mustard seed
Contributes pungent, sharp heat that develops as the seeds cook in the liquid.
Onions
Add savoury depth and body as they soften during the long boil.

The step that matters

Boil all ingredients together until well done. The sauce must cook long enough for the tomatoes and onions to soften fully and the mixture to thicken, while the vinegar's sharpness mellows. Stopping early leaves chunky, raw-tasting pieces and a harsh, thin sauce.

Swap the onion

How well each one fits the dish's main ingredients (tomato, mustard, pepper, allspice, celery, sugar, vinegar):
