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 Stew
Ingredients
Directions
Prepare the fish
Clean and wash the fish, cut into pieces, salt and let sit for 15‑20 minutes.
Dry each piece with a clean cloth, dredge with flour and fry in hot oil on both sides.
Make the stew
Fry the chopped onion in the oil that remained from the fish frying.
When the onion starts to turn yellow, add the tomato sauce, wine, salt, pepper, juniper berries, lemon slices and fish pieces.
Place in the oven at low temperature and let it bake until the liquid is reduced.
Serve
Serve warm or cold.

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 stew, becoming tender as it cooks gently in the sauce.
- Flour
- Dusting the fish creates a light coating that browns when fried and helps hold the pieces together.
- Onions
- Soften and turn sweet as they cook, building the base flavour of the stew.
- Wine
- Adds acidity and aroma, and its liquid reduces during baking to concentrate the sauce.
- Tomato sauce
- Adds body, colour and savoury sweetness to the liquid in the stew.
The step that matters
Frying the floured fish on both sides. Flour coating must be dry and the oil hot, otherwise the coating absorbs oil and turns soggy instead of forming a light golden crust that holds the pieces together.
