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 and tart flavor that forms the relish base.
- Coarse sea salt
- Draws water out of the vegetables, firming them and concentrating their flavor.
- Vinegar
- Adds acidity that gives the relish its sharp tang and helps preserve it.
- Sugar
- Balances the sharpness of the vinegar and mustard with sweetness.
- Mustard seed
- Contributes pungent heat and a crunchy texture when cooked in the relish.
- Onions
- Add savory depth and aroma as the vegetables cook down.
The step that matters
Drain the vegetables well. Salting draws out a lot of water; any left behind dilutes the vinegar and leaves the relish watery and less crisp.
