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 body of the pickle, absorbing salt and vinegar flavour as they soften.
Coarse sea salt
Draws out bitterness and moisture from the walnuts during soaking and brining.
Strong vinegar
Acts as the preserving liquid, adding sharp acidity that keeps the walnuts stable in the jar.
Blades of mace
Adds warm, aromatic spice flavour that infuses the walnuts as they pickle.
Nutmeg
Adds warm, sweet aroma that complements the mace in the pickling liquid.

The step that matters

Simmer without boiling. Gentle simmering softens the walnuts evenly. A rolling boil would toughen and break them apart, so keep the liquid just below the boil.

Swap the mace

How well each one fits the dish's main ingredients (walnut, nutmeg, vinegar):

  1. Cinnamonfits better
  2. Allspicefits better
  3. Tarragonfits better
  4. Macethe original

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