Why it works: Capers and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,550 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Broiled Carp with Caper Sauce
Ingredients
Directions
Prepare the carp
Kill the carp by striking its head with a large knife.
Remove the scales starting from the tail, then the belly and the other side.
Remove the gills carefully without damaging the tongue.
Make small incisions in the neck and belly to remove the roe, intestines, and guts.
Wash the carp thoroughly until no blood remains and wipe it dry.
Slit both sides of the back and marinate in oil, salt, and pepper for about an hour.
Broil and make the sauce
Broil the carp over a slow fire until cooked through, turning occasionally.
For the sauce, melt ¼ pound of butter in a saucepan, add flour, salt, nutmeg, pepper, vinegar, and enough water to thicken. Stir the sauce over heat until combined and thickened.
Serve
Serve the broiled carp with caper sauce and garnish with chopped parsley and butter inside the body.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp
- Is the main protein; broiling cooks its flesh through while the marinade seasons it.
- Oil
- Carries the seasoning into the fish and helps keep the surface from drying during broiling.
- Butter
- Enriches the sauce with fat, adding richness and a smooth mouthfeel.
- Flour
- Thickens the butter and water into a smooth sauce as it cooks.
- Capers
- Add a sharp, briny flavour that contrasts with the rich butter sauce.
The step that matters
Stirring the sauce over heat after adding the flour. Flour must be cooked with the melted butter and stirred continuously; otherwise it stays lumpy and tastes raw, and the sauce may scorch on the bottom of the pan.
Swap the nutmeg
How well each one fits the dish's main ingredients (pepper, capers, parsley, butter, vinegar, sauce, flour):
- Tarragonfits better
- Dillfits better
- Thymefits better
- Nutmegthe original
Fit is the average pairing score against pepper, capers, parsley, butter, vinegar, sauce, flour. Candidates are from the same food group and used in at least 100 recipes.
