Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cabbage
- Provides the bulk and a firm, crisp texture in the finished relish.
- Cucumbers
- Adds crunch and fresh body to the chopped mixture.
- Green tomatoes
- Contributes tartness and body to the relish.
- Sugar
- Balances the sharpness of the vinegar and adds sweetness.
- Vinegar
- Acidity that preserves the vegetables and gives the relish its tang.
The step that matters
Pour off the vinegar after the 24-hour stand. Salt and the initial vinegar draw water out of the vegetables. Pouring off the liquid before adding sugar and fresh boiling vinegar keeps the pickle from becoming watery and diluted.
Swap the mace
