Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green walnuts
- Unripe walnuts are the base of the pickle, softening and darkening as they steep in vinegar.
- Vinegar
- Acid preserves the walnuts and draws out their flavour, giving the pickle its sharp character.
- Coarse sea salt
- Salt seasons the walnuts and helps draw out their bitterness during the initial soak.
- Allspice
- Adds warm, aromatic spice that flavours the pickling liquor.
The step that matters
Sealing the walnuts during the long steep. Walnuts must stay fully covered in vinegar and sealed in a cool, dry place for months, so the acid can preserve them and the flavour can develop evenly without spoilage.
Swap the walnut
