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 chopped vegetable base, softening during salting and simmering.
- Cabbage
- Adds body and crunch to the relish after salting and cooking.
- Sugar
- Balances the sharpness of the vinegar and adds sweetness to the relish.
- Strong vinegar
- Provides acidity that preserves the relish and gives it its tang.
- Ripe tomatoes
- Add moisture and sweet, mellow flavor to the cooked relish.
- Horseradish root
- Contributes sharp pungency that mellows during the long aging period.
The step that matters
Drain the juice thoroughly. Salting draws out a large amount of liquid from the vegetables. If the juice is not removed, the relish will be watery and diluted, and the vinegar balance will be off.
Swap the tomato
