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 slightly while absorbing the spiced vinegar.
Onions
Add sweetness and body that softens as the salted vegetables pickle.
Vinegar
Provides the acidity that preserves and sharpens the pickle.
Brown sugar
Balances the sharp vinegar with sweetness and depth.
White mustard seed
Adds a sharp, pungent flavour that mellows during simmering.
Salt
Draws water out of the sliced vegetables, firming them before pickling.

The step that matters

Draining after the overnight salting. Salt draws out a lot of liquid; if the vegetables are not well drained, the pickling liquid is diluted and the pickle can turn watery and less crisp.
