Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the relish and hold their shape as pieces of vegetable.
- Onions
- Add savory bulk and a sharp, sweet flavor that mellows during cooking.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Acidity that preserves the relish and gives it its tangy character.
- Mustard-seed
- Contributes pungent, sharp flavor when cooked in the vinegar mixture.
- Gherkins
- Add crunch and a tangy, pickled flavor to the relish.
The step that matters
Salting and standing the sliced vegetables for 12 hours. Salt draws water out of the vegetables by osmosis, so they release liquid and firm up. Skipping or shortening this rest leaves the relish wetter and softer after cooking.
Swap the mace
