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 base that the pickle is built from.
- Coarse sea salt
- Draws water out of the chopped vegetables overnight, firming them and concentrating flavor.
- Vinegar
- Provides acidity that preserves the pickle and gives it its sharp tang.
- Mustard seed
- Adds pungent, slightly bitter flavor and a bit of crunch to the mix.
- Horseradish
- Contributes sharp, pungent heat that mellows as the pickle sits.
The step that matters
Drain the mixture well in the morning. Salt draws moisture out of the chopped vegetables overnight. Draining thoroughly removes that liquid so the pickle stays firm and is not watery once the boiling vinegar is added.
