Why it works: Allspice and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 7,874 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Pickled Walnuts
Ingredients
Directions
Prepare
Clean the walnuts and pack them in a jar.
Mix allspice, black pepper, long pepper, ginger, cloves, nutmeg, and mustard flour together.
Strew the spice mixture between the layers of walnuts.
Pickle

If walnuts are hard, boil them again, adding garlic in the last boiling.
Seal the jar tightly and do not open for 4 months.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Walnuts
- Are the main body of the pickle, softening and taking on the spiced vinegar flavour over time.
- Vinegar
- Acts as the pickling liquid, preserving the walnuts and carrying the spice flavour into them.
- Allspice
- Adds warm, aromatic flavour that defines the pickle's character.
- Black pepper
- Adds sharp, pungent heat that balances the sweetness of the walnuts.
- Mustard flour
- Adds pungency and sharpness that contributes to the pickle's tang.
The step that matters
Pouring the boiling vinegar over the walnuts. Hot vinegar penetrates the walnuts and helps keep the pickle preserved; repeating the boil three times is what gives the vinegar a chance to work through the nuts and drive out the flavour.
Swap the clove
The recipe marks clove as optional. How well each one fits the dish's main ingredients (walnut, allspice, pepper, ginger, nutmeg, mustard, flour):
- Cinnamonfits better
- Clovethe original
- Turmericfits about as well
- Cardamomfits about as well
Fit is the average pairing score against walnut, allspice, pepper, ginger, nutmeg, mustard, flour. Candidates are from the same food group and used in at least 100 recipes.
