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 scaled and gutted carp in a saucepan with water, white wine, pepper, salt, mace, sweet herbs, onions, and horseradish.
Cover the pan and simmer for 1.5 hours.
Make the sauce

Boil for a few minutes.
Add egg yolks mixed with a little cream.
Squeeze lemon juice into the sauce.
Serve
Pour sauce over the fish before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp
- Is the main fish that is cooked gently in the simmering liquid until tender.
- Egg yolks
- Thicken the sauce into a smooth, creamy texture when gently heated.
- Butter
- Adds richness and body to the sauce, helping it feel smooth on the palate.
- Anchovies
- Add savoury depth to the sauce, which melts into it during cooking.
- Lemon juice
- Adds acidity that brightens the rich cream and butter sauce.
The step that matters
Adding egg yolks to the sauce. Egg yolks thicken through gentle heat. If the sauce boils after they go in, they can scramble and turn grainy, so keep it warm and stir constantly.
