Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green walnuts
- Provide the main pickled ingredient, softening and darkening as they steep in vinegar.
- Vinegar
- Acts as the preserving liquid, its acidity keeping the walnuts stable and sharply flavoured.
- Allspice
- Adds warm, aromatic spice flavour that infuses into the pickling vinegar.
- Cloves
- Contribute strong aromatic spice notes to the pickling liquid.
The step that matters
Covering the walnuts with boiling vinegar. The walnuts must stay fully submerged in the hot vinegar, since any exposed pieces can spoil. Pouring boiling vinegar also helps extract the spice flavours and begins to sterilise the jars before sealing.
