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 ↓
To Stew Carp
Ingredients
Directions
Stew the carp
Place the carp in a stewpan with the meat broth or fish gravy.
Add the white wine, onions, horseradish, sweet herbs, cayenne, black pepper, and salt.
Let the mixture stew for about 1.5 hours.
Make the sauce
In a small saucepan, combine white wine, anchovies, onion, lemon peel, cream, and some of the fish cooking liquid.
Add the beaten egg yolks and gently boil for a few minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the cream sauce as they set when gently heated.
- Thick cream
- Adds richness and body to the sauce, softening its flavor.
- Anchovies
- Contribute savory depth that rounds out the sauce.
- Horseradish
- Adds sharp, pungent heat that mellows during stewing.
The step that matters
Boiling the egg yolks into the sauce. Egg yolks thicken by setting when heated, but if they get too hot or boil hard they can curdle and turn grainy. Keep the heat gentle and stir well.
Swap the onion
How well each one fits the dish's main ingredients (meat, white wine, horseradish, pepper, lemon, cream, egg):
