Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Form the bulk of the pickle and give it its main body and texture.
- Vinegar
- Provides the sharp acidity that gives the pickle its tang and helps preserve it.
- Brown sugar
- Adds sweetness that balances the acidity of the vinegar.
- Mustard
- Adds a sharp, pungent flavor to the sweet and sour base.
- Horseradish
- Adds a hot, pungent bite to the pickle.
- Cabbage
- Adds crunch and bulk to the finely chopped vegetable mixture.
The step that matters
Drain the tomatoes until dry. Salt draws water out of the tomatoes overnight. If they are not drained well, the extra liquid dilutes the vinegar mixture and leaves the pickle watery and less firm.
