Why it works: Horseradish and roe work together. They rank in the top 13% of all ingredient pairs, and 43 recipes mention both. Both carry eugenol, which smells clove, spicy. The science ↓
The recipe
Ingredients
Contains: milk, wheat, fish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the fish
Clean and gut the fish, then wash thoroughly and dry with a cloth.
Sprinkle flour over the fish and fry in dripping or sweet-rendered suet until light brown.
Stew
Place the fish in a stew pan with water, red wine, lemon pickle, browning sauce, mushroom powder, cayenne pepper, the onion with cloves, and horseradish.
Cover the pan and stew gently over low heat until the gravy reduces to just 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, and pour over the fish.
Garnish with pickled mushrooms, scraped horseradish, and roe, some fried and cut into small pieces, the rest boiled.
Just before serving, squeeze lemon juice into the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carp or tench
- Forms the main body of the dish, cooked gently until tender in the gravy.
- Flour
- Light browning coat on the fish, and thickens the gravy when rolled with butter.
- Red wine
- Adds acidity and depth of flavour to the stewing liquid.
- Butter
- Enriches the gravy and adds richness and a smooth finish when rolled in flour.
- Horseradish
- Contributes a sharp, pungent aroma that mellows during stewing.
The step that matters
Stewing gently until the gravy reduces. Low, covered heat keeps the fish moist and tender while the liquid concentrates. Boiling hard would break up the flesh and make the gravy cloudy or tough.

Fit is the average pairing score against flour, red wine, lemon, sauce, mushroom, pepper, clove. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
