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 bulk and bitter, earthy flavor that the soaking and brining gradually mellow.
Coarse salt
Draws moisture out of the walnuts and helps draw out bitterness during brining.
Vinegar
Adds acidity that preserves the walnuts and gives the pickle its sharp, tangy character.
Sugar
Balances the sharpness of the vinegar with sweetness.
Ginger
Adds warm, pungent aroma to the pickling liquid.
Garlic
Adds pungent savory aroma that deepens as the pickle rests.

The step that matters

Boiling walnuts until soft. Walnuts that are under-boiled stay firm and may taste harsh, while overcooking breaks them down. Soft, evenly cooked walnuts absorb the pickling liquid more evenly.

Swap the mace

How well each one fits the dish's main ingredients (walnut, vinegar, cinnamon, clove, sugar, ginger, garlic):

  1. Allspicefits better
  2. Cardamomfits better
  3. Nutmegfits better
  4. Macethe original

Fit is the average pairing score against walnut, vinegar, cinnamon, clove, sugar, ginger, garlic. Candidates are from the same food group and used in at least 100 recipes.
