Why it works: Lemon and pepper 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 ↓
Stewed Carp
Ingredients
Directions
Prepare
Scale and clean the carp; if large, cut into pieces.
Rub a little coarse sea salt on the fish and place it in a stewpan.
Stew
Add enough stock to cover the fish, along with the onions, herbs, and spices.
Stew gently for about 1 hour, or longer if the fish is very large.
Make the sauce and serve
Carefully dish up the fish, strain the cooking liquid, and add the port wine, lemon juice, and cayenne.
Bring the sauce to a boil, pour it over the fish, and serve.

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, cooked gently in stock until tender.
- Port wine
- Adds depth, mild sweetness and acidity to the finished sauce.
- Lemon juice
- Adds acidity that brightens the sauce and balances the port.
- Onions
- Release sweetness and aromatic flavour into the stewing liquid.
The step that matters
Stew gently for about 1 hour. Gentle heat cooks the fish through while keeping its flesh moist and intact. A hard boil toughens the protein and breaks the fish apart, so the liquid should only simmer.
Swap the onion
How well each one fits the dish's main ingredients (fish, clove, mace, port wine, lemon, pepper):
