Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Vinegar
Provides the acidity that preserves the vegetables and gives the pickle its sharp flavour.
Cauliflower
Forms the firm, crisp body of the pickle.
Green tomatoes
Adds bulk and a tart, firm texture that holds up to pickling.
Mustard
Contributes the pungent, sharp flavour that defines the pickle.
Sugar
Balances the sharpness of the vinegar with sweetness.
Flour
Thickens the pickling liquid so it clings to the vegetables.

The step that matters

Repeating the boil in vinegar over three days. Each boil softens the vegetables and drives in vinegar. Boiling too hard or too long can turn them mushy, while too few repeats may leave them crisp and under-preserved.
