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

What each ingredient does

Best brown vinegar: Provides the sharp acidity that gives the pickling liquid its sourness and preserving power.
Mustard seed: Adds a sharp, pungent flavour that builds as the seeds steep in the liquid.
Turmeric: Gives the pickle a bright yellow colour and an earthy, slightly bitter flavour.
Cayenne pepper: Adds direct heat from capsaicin, which spreads through the liquid as it steeps.
Long pepper: Adds warm, pungent heat with a slightly sweet, peppery aroma.
Bruised ginger: Releases aromatic oils and a warm, gingery flavour into the vinegar.
