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 body and tartness that the pickle is built around.
- Coarse sea salt
- Draws moisture out of the vegetables overnight, firming them and concentrating flavor.
- Mustard seed
- Adds pungent, sharp flavor that carries through the vinegar brine.
- Grated horseradish
- Contributes sharp, pungent heat that intensifies as it sits in the vinegar.
- Boiling vinegar
- Acidifies the mixture, providing the sour preserving brine that gives the pickle its tang.
The step that matters
Drain the salted mixture well. Salt has drawn water out of the vegetables overnight. If excess liquid stays, the boiling vinegar is diluted and the pickle turns watery and less crisp, so thorough draining keeps the texture firm.
Swap the tomato
How well each one fits the dish's main ingredients (onion, pepper, mustard, allspice, clove, horseradish, vinegar):
