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 ↓

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 being preserved, so they absorb the pickling liquid.
- Vinegar
- Provides the acidity that preserves the fish and gives the pickle its sharp flavour.
- Sugar
- Balances the sharpness of the vinegar and rounds out the sweet-sour flavour.
- Saltpetre
- Helps preserve the fish and keeps its colour firm during pickling.
- Port wine
- Adds sweetness and a rich, fruity aroma to the pickling liquid.
The step that matters
Pour the cooled mixture over the smelts. Pouring the liquid over smelts while it is still hot can partly cook the delicate fish and make it soft. Letting it cool first keeps the texture firm and lets the acid penetrate evenly.
Swap the mace
How well each one fits the dish's main ingredients (smelt, port wine, lemon, vinegar, ginger, nutmeg, pepper):
- Clovefits better
- Allspicefits better
