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 relish and release moisture that the salt draws out.
- Cabbage
- Adds body and crisp texture to the chopped vegetable mass.
- Cider vinegar
- Provides acidity that gives the relish its tang and helps preserve it.
- Brown sugar
- Adds sweetness that balances the sharp vinegar and tomatoes.
- Onions
- Contribute savory depth and aroma as they soften during the long boil.
- White mustard seed
- Adds pungent, sharp flavour that deepens during cooking.
The step that matters
Draining the salted vegetables thoroughly. Salt draws water out of the vegetables over 24 hours. If they are not drained well, excess liquid dilutes the vinegar and sugar mixture, so the relish cooks watery and loses flavour and body.
