Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
To Pickle Smelts
Ingredients
Directions
Prepare
Lay the smelts in rows in a jar.
In a pot, combine red port, lemon slices, vinegar, ginger, nutmeg, mace, pepper, coarse sea salt, cochineal, saltpetre, sugar, and bay leaf.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Smelts
- Are the main fish that are preserved and flavoured by the pickling liquid.
- Vinegar
- Provides the acidity that preserves the fish and sharpens the flavour of the pickle.
- Red port
- Adds sweetness and depth to the pickling liquid.
- Sugar
- Balances the sharpness of the vinegar and rounds out the flavour.
- Saltpetre
- Helps preserve the fish and keeps the flesh firm and colour stable during storage.
- Cochineal
- Adds a red colour to the pickling liquid.
The step that matters
Boil the mixture, skim it clean, and pour it over the smelts. Boiling the hot vinegar liquor helps it penetrate and preserve the fish, and skimming removes impurities that could spoil the pickle. Pouring it over the fish while it is hot starts the pickling process.
