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 ↓
Carp Stewed White
Ingredients
Directions
Poach the carp
Place the carp in a stewpan with water, white wine, pepper, salt, mace, sweet herbs, onions, and horseradish.
Cover the pan and simmer for 1.5 hours.
Make the sauce
In a separate saucepan, combine white wine, onion, anchovies, butter, lemon peel, cream, and the cooking liquid from the carp. Boil for a few minutes.
Add egg yolks mixed with cream. When it boils, squeeze in lemon juice.
Serve
Pour the sauce hot over the fish. Serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp
- Forms the main body of the stew, providing the fish that the sauce is poured over.
- Egg yolks
- Thicken the sauce as they gently set with heat, giving it a smooth, rich body.
- Butter
- Adds richness and fat to the sauce, and flour coating helps it thicken smoothly.
- Cream
- Adds richness and body to the sauce, softening its flavour.
- Anchovies
- Add savoury depth to the sauce, blending into the background rather than tasting strongly fishy.
- Lemon juice
- Adds acidity that brightens the rich sauce and balances its fat.
The step that matters
Adding the egg yolks. Egg yolks thicken when heated gently, but if the sauce boils after they go in, they can curdle and turn grainy. Add them off the heat or at low heat, stirring constantly, and keep the sauce below a boil.
Swap the mace
How well each one fits the dish's main ingredients (white wine, pepper, onion, horseradish, butter, flour, lemon):
- Parsleyfits better
- Thymefits better
- Tarragonfits better
- Macethe original
Fit is the average pairing score against white wine, pepper, onion, horseradish, butter, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
