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 Tickle Smelts
Ingredients
Directions
Prepare
Arrange 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.
Pickle and store
Boil the mixture, skim it clean, and pour it over the smelts.
Once cool, drizzle a little sweet oil over the smelts.
Seal the jar tightly with bladder and leather.
Store it in a cool place.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Smelts
- The fish being preserved; they firm and take on the pickling flavour as they sit in the brine.
- Vinegar
- Its acidity preserves the fish and gives the pickle its sharp, tangy character.
- Sugar
- Balances the sharpness of the vinegar and port with a touch of sweetness.
- Red port
- Adds sweetness, body and depth of flavour to the pickling liquid.
- Saltpetre
- Helps keep the fish's colour and firmness during long curing in the brine.
- Lemon
- Adds citrus acidity and aroma to the pickling liquid.
The step that matters
Pour the boiled mixture over the smelts and let it cool. Boiling the brine dissolves the spices and sugar and drives off raw harshness, while cooling before sealing prevents heat from softening the fish. The acidic liquid must cover the fish so it is protected from spoilage during storage.
