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
- Lampreys
- The main fish, cooked through in butter and then bathed in the sauce.
- Fresh butter
- Fat for frying, adding richness and browning to the fish.
- White wine
- Adds acidity and aroma to the pan liquid that becomes the sauce.
- Flour
- Butter rolled in flour thickens the sauce slightly as it melts in.
- Lemon
- Squeezed in to brighten the sauce with acidity.
The step that matters
Adding the saved blood. Blood is a protein-rich liquid that thickens when heated gently and can curdle if it boils hard. Add it with the butter and flour, keep shaking the pan, and avoid a rolling boil until the sauce is finished, so it thickens smoothly instead of separating.
Swap the capers
How well each one fits the dish's main ingredients (butter, white wine, pepper, nutmeg, flour, lemon):
- Marjoramfits better
- Parsleyfits better
- Thymefits better
- Capersthe original
Fit is the average pairing score against butter, white wine, pepper, nutmeg, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
