Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Provide the bulk of the sauce and soften into a tender, chunky texture when boiled.
- Onions
- Add savory depth and body, softening into the sauce as it cooks.
- Brown sugar
- Adds sweetness and helps balance the sharpness of the vinegar.
- Vinegar
- Provides acidity that preserves the sauce and sharpens its flavour.
- Ground mustard
- Contributes a sharp, pungent bite that complements the vinegar and sugar.
The step that matters
Boil the tomatoes and onions until tender. Boiling long enough softens the vegetables fully, while the sugar and vinegar must be balanced to taste; adding more vinegar or sugar as needed keeps the sauce from becoming too sharp or too sweet.
Swap the celery
