Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and 27,039 recipes mention both. Both carry 2-nonenal, which smells fatty, green. 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
Wash and dry the fish thoroughly with a cloth.
Stew
Place the fish in a stew pan with water, red wine, lemon pickle, browning sauce, mushroom powder, cayenne pepper, onion, 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 from the pan.
Place the fish on a serving dish.
Thicken the gravy with butter rolled in flour.
Boil the gravy briefly.
Strain the gravy over the fish.
Garnish with pickled mushrooms, scraped horseradish, and fish roes (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.
- Red wine
- Adds depth, acidity and color to the gravy as it reduces.
- Butter
- Enriches the gravy and, with flour, gives it a smooth, thickened body.
- Flour
- Thickens the gravy when rolled with butter and boiled briefly.
- Fish roes
- Adds rich texture and savory flavor as a garnish, fried for crispness and boiled for softness.
The step that matters
Stewing gently over low heat. Low, gentle heat keeps the delicate fish flesh from breaking apart while the gravy slowly reduces and concentrates its flavor.
Flavor stand-ins for the onion
How well each one fits the dish's main ingredients (fish, red wine, lemon, sauce, mushroom, pepper, clove):

- Onionthe original
Fit is the average pairing score against fish, 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).
