Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Young walnuts
Provide the main flavor and aroma as their oils and compounds steep into the brandy.
Brandy
Acts as the solvent that extracts flavor from the walnuts and preserves the liquid.
Sugar
Adds sweetness and balances the bitterness and alcohol burn of the infusion.

The step that matters

Stirring during the month-long infusion. Regular stirring keeps the crushed walnut pieces in contact with the brandy, so flavor extracts evenly instead of settling at the bottom of the jar.

Swap the walnut

How well each one fits the dish's main ingredients (brandy, sugar, nutmeg, clove):

  1. Chestnutfits better
  2. Almondfits better
  3. Walnutthe original
  4. Pistachiofits about as well

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