Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green tomatoes
- Make up the bulk of the pickle and add a tart, fresh body.
- Coarse sea salt
- Draws water out of the vegetables overnight, firming them and concentrating flavor.
- Mustard seed
- Adds a sharp, pungent bite that carries through the pickle.
- Ground allspice
- Contributes warm, aromatic spice notes.
- Boiling vinegar
- Provides acidity that sharpens flavor and helps preserve the pickle.
- Grated horseradish
- Adds sharp, pungent heat that fades as the pickle rests.
The step that matters
Drain the mixture well. Draining removes the water the salt drew out overnight. Leftover liquid dilutes the boiling vinegar, which can make the pickle taste weak and its texture soft.
