Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. 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, ensuring they come off in one piece.
Remove the gills without damaging the tongue.
Make small incisions in the neck and belly to remove the roe, intestines, and guts.
Wash the carp thoroughly and wipe it dry.
Slit both sides of the back and marinate in oil, salt, and pepper for about an hour.
Cook and serve
Place the carp on a grill over low heat and broil for 20-30 minutes, turning occasionally.
Prepare the caper sauce by melting butter in a saucepan, adding flour, and stirring until combined.
If the carp has soft roe, mix it with chopped parsley and a small amount of butter, then sew the belly shut.
Once cooked, remove the thread and serve the carp with the caper sauce.

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 dish, so its flesh sets the texture and flavour.
- Butter
- Adds richness and fat to the caper sauce and carries flavour.
- Flour
- Thickens the butter into a roux that gives the sauce body.
- Essence of anchovies
- Adds a salty, savoury depth to the sauce.
The step that matters
Broil over low heat with occasional turning. Fish flesh is delicate and dries out or sticks when heat is too high or it is left unturned. Low, steady heat and turning help the carp cook through evenly while staying moist.
Swap the parsley
How well each one fits the dish's main ingredients (pepper, butter, flour):
- Parsleythe original
- Turmericfits about as well
- Nutmegfits about as well
- Sagefits less well
Fit is the average pairing score against pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
