Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomatoes
- Provide the bulk of the relish and release moisture that the salt draws out.
- Cabbage
- Adds crisp texture that holds up after salting and pickling.
- Cider vinegar
- Provides the sharp acidity that preserves and flavors the relish.
- Brown sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Celery seed
- Contributes a warm, aromatic flavor to the pickling liquid.
The step that matters
Salting the chopped vegetables overnight. Salt draws water out of the vegetables through osmosis. Too little salt or too short a rest leaves them watery and soft, which dilutes the hot vinegar and weakens the crisp texture.
