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 as they cook in the vinegar.
Onions
Add savory flavor and body to the pickle.
Coarse sea salt
Draws water out of the tomatoes and onions so they stay firmer.
Vinegar
Provides the sharp acidity that preserves and flavors the pickle.
Brown sugar
Adds sweetness that balances the sharpness of the vinegar.
Mustard seed
Contributes a sharp, pungent flavor to the pickling liquid.

The step that matters

Draining after the salt rest. Salt draws out a lot of liquid overnight. Draining it well, and boiling in fresh vinegar and water, removes excess salt and moisture so the pickle stays firm and is not overly salty.

Swap the onion
