Why it works: Ginger and clove match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 6,038 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Pickled Walnuts
Ingredients
Directions
Prepare the walnuts
Prick the walnuts and soak them in brine for a week.
When they turn black, drain them on a sieve for 3-4 hours.
Dry them with a cloth.
Pickle and store
Place them in jars or bottles.
Pour vinegar over the walnuts, ensuring they are fully covered.
Seal the jars and store them away from the air.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vinegar
- Its acidity preserves the walnuts and gives the pickle its sharp, tangy flavour.
- Mustard seed
- Adds a pungent, sharp flavour that deepens as the walnuts pickle.
- Ground black pepper
- Contributes a sharp, warm bite to the pickling liquid.
- Ground ginger
- Adds a warm, aromatic spice note to the pickle.
The step that matters
Covering the walnuts fully with vinegar. Walnuts left exposed above the liquid can spoil. The vinegar's acidity only protects the nuts it fully surrounds, so every piece must stay submerged.
Swap the mace
How well each one fits the dish's main ingredients (vinegar, pepper, ginger, clove, mustard):
- Allspicefits better
- Turmericfits better
- Cinnamonfits better
- Macethe original
Fit is the average pairing score against vinegar, pepper, ginger, clove, mustard. Candidates are from the same food group and used in at least 100 recipes.
