To Fickle Walnuts

Ingredients

Directions

Prepare the walnuts

  1. Pare the walnuts until the white appears, being careful not to cut too deep.

  2. Soak the walnuts in saltwater to prevent them from turning black.

  3. Boil the walnuts in salted water for five minutes.

  4. Spread the boiled walnuts between two clean cloths to cool.

Pickle and store

  1. Place the cooled walnuts in wide-mouthed bottles.

  2. Fill the bottles with distilled vinegar and add a blade or two of mace and a large teaspoon of eating oil.

  3. Cork the bottles well and store them in a dry place.

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

What each ingredient does

Large french walnuts
Form the pickle's main body, absorbing the vinegar flavour as they steep.
Distilled vinegar
Acidity that preserves the walnuts and gives the pickle its sharp, tangy taste.
Mace
Adds warm, aromatic spice flavour that infuses the walnuts during pickling.
Eating oil
Forms a thin layer on the surface that helps seal the walnuts from air.

The step that matters

Paring the walnuts. Cutting too deep removes flesh and exposes the inside to air, and the walnuts can darken. Soaking in salted water protects the cut surfaces from browning, which is why the record's soaking step matters.

Swap the mace

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

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

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