Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Provides the bulk of the relish and a crisp texture once cooked.
- Green tomatoes
- Add tartness and body to the relish.
- Onions
- Contribute savory depth and aroma as they soften.
- Sea salt
- Draws water out of the vegetables, helping them stay crisp and firm.
- Vinegar
- Adds acidity that gives the relish its sharp flavor and helps preserve it.
- Sugar
- Balances the acidity and helps thicken the syrup.
The step that matters
Salting overnight. Salt pulls moisture out of the chopped vegetables through osmosis. Skipping or shortening this rest leaves extra water in the relish, which dilutes the syrup and can make the finished chow chow watery and less firm.
