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.
