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 chow-chow and release moisture that the salt draws out.
- Cabbage
- Adds crisp texture and body to the chopped vegetable mixture.
- Cider vinegar
- Provides acidity that preserves the mixture and balances the sweetness.
- Brown sugar
- Adds sweetness and depth, and helps balance the vinegar's sharpness.
- Horseradish
- Adds pungent heat that gives the relish its sharp, sinus-clearing bite.
- Celery
- Adds crunch and a mild, savory vegetable flavor to the mixture.
The step that matters
Drain the salted mixture thoroughly. Salt draws water out of the chopped vegetables over 24 hours. Removing that liquid before cooking keeps the chow-chow from becoming watery and helps it hold a thicker, more spoonable texture.
