Why it works: Pepper and allspice match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 6,395 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Pickled Walnuts
Ingredients
Directions
Prepare the walnuts
Soak the walnuts in strong brine for 6 days.
Drain and wipe the walnuts dry, then pierce them with a large needle.

Pack and pickle
Pack the walnuts into jars.
Boil the vinegar with sugar, pepper, mace, and allspice for 6 minutes, then pour it over the walnuts.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- The main ingredient, which softens and takes on the pickling flavours as it stands in the vinegar.
- Vinegar
- Provides the sharp acidity that preserves the walnuts and gives the pickle its tang.
- Sugar
- Balances the sharpness of the vinegar with sweetness.
- Whole pepper
- Adds warm, pungent aroma to the pickling liquor.
- Mace
- Adds a warm, aromatic spice flavour to the pickling liquor.
- Whole allspice
- Adds a clove-like, aromatic spice flavour to the pickling liquor.
The step that matters
Piercing and soaking the walnuts. Piercing the walnuts lets the vinegar penetrate the nut. Draining and wiping them dry before piercing keeps excess brine out of the jars, so the vinegar stays clear and the pickle keeps well.
Swap the mace
How well each one fits the dish's main ingredients (sugar, pepper, allspice, walnut, vinegar):
- Cinnamonfits better
- Clovefits better
- Nutmegfits better
- Macethe original
Fit is the average pairing score against sugar, pepper, allspice, walnut, vinegar. Candidates are from the same food group and used in at least 100 recipes.
