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

What each ingredient does

Walnuts
Form the main body of the pickle and absorb the flavour of the vinegar.
Vinegar
Acts as the preserving liquid and provides the sharp, acidic bite.
Black pepper
Adds warm, sharp spice that carries through the pickling liquid.
Cloves
Contribute strong aromatic spice to the pickling liquid.
Ginger
Adds warm, aromatic pungency to the spiced vinegar.
Mustard seed
Adds a pungent, slightly bitter note and texture when layered on top.

The step that matters

Keep the walnuts hot without boiling. Holding the walnuts just below boiling for twelve hours softens them and lets them take up flavour without breaking apart. Boiling can toughen or split the nuts.
