Why it works: Pepper and lemon 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
- Calf's liver
- Forms the main body of the dish, cooked quickly to stay tender.
- Madeira wine
- Reduces to a concentrated, slightly sweet flavour that deglazes the pan.
- Mushroom sauce
- Supplies moisture and savoury depth to coat the liver.
- Butter
- Adds fat for frying and a rich finish that gives the sauce body.
- Lemon juice
- Adds acidity that brightens the rich liver and wine sauce.
The step that matters
Add the butter and lemon juice without boiling. Butter is an emulsifier that thickens and enriches a sauce, but if it boils the emulsion can break and turn greasy. Tossing gently off the heat or at low heat keeps the sauce smooth and the lemon flavour fresh.
