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 ↓
Stewing Fish
Ingredients
Directions
Prepare the fish
Wash the fish thoroughly.
Dry the fish with a cloth.
Sprinkle flour over the fish.
Fry the fish in dripping or suet until light brown.
Make the stew
In a stew pan, combine water, red wine, lemon pickle, browning sauce, mushroom powder, cayenne pepper, onion, and cinnamon stick.
Add the fish (and blood if using carp).
Cover the fish with the mixture.
Stew gently over low heat until the gravy reduces to cover the fish.
Thicken and serve
Remove the fish and place it on a serving dish.
Thicken the gravy with butter rolled in flour.
Boil briefly.
Strain the gravy over the fish.
Garnish with pickled mushrooms, scraped horseradish, and fish roe, some fried and some boiled.
Squeeze lemon juice into the sauce before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Fish
- Forms the main body of the dish, cooked gently in the gravy until tender.
- Flour
- Coats the fish so it browns during frying, and thickens the gravy with butter.
- Red wine
- Adds acidity and depth to the gravy as it reduces.
- Butter
- Enriches the gravy and, rolled in flour, thickens it as it melts in.
- Fish roe
- Adds richness and texture as a garnish, both fried and boiled.
The step that matters
Thicken the gravy with butter rolled in flour. Adding the butter and flour mixture to a boiling liquid without first letting it cook briefly can leave lumps and a raw floury taste. Whisking it in and boiling briefly lets the starch swell evenly and thicken the gravy smoothly.
Swap the onion
How well each one fits the dish's main ingredients (fish, flour, red wine, lemon, sauce, mushroom, pepper):
- Shallotfits better
- Capsicumfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against fish, flour, red wine, lemon, sauce, mushroom, pepper. Candidates are from the same food group and used in at least 100 recipes.
