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 soften into tender pieces during cooking.
Onions
Add sweetness and savory flavor that balances the vinegar.
Vinegar
Provides acidity that preserves the pickle and gives it its sharp taste.
Brown sugar
Adds sweetness and depth that offsets the acidity of the vinegar.
Coarse sea salt
Draws moisture out of the vegetables, firming them before cooking.
Horseradish
Contributes a sharp, pungent heat that develops after cooling.

The step that matters

Drain the vegetables after salting. Salting draws out a lot of water; draining well before adding vinegar keeps the liquid from diluting the brine and keeps the pickle firm rather than soggy.

Swap the tomato
