What each ingredient does
- Walnuts
- Provide the main body and rich, oily flavour of the snack.
- Coarse kitchen salt
- Seasons the walnuts and draws out their savoury flavour.
- Vinegar
- Acidity in the soaking water helps slow browning of the cut walnut meat.
The step that matters
Soaking in vinegar water. Cut walnut surfaces oxidise and darken quickly when exposed to air. The acidified cold water slows this browning, so the halves should be soaked promptly after splitting and drained well before salting so the salt sticks.
