Why it works: Beef and mushroom are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,232 recipes. Both carry 2,4-nonadienal, which smells fatty, green. The science ↓
To Dress Haddocks with Brown Sauce
Ingredients
Directions
Prepare the haddock
Gut and clean the haddocks, then wipe them with a cloth.
Keep the breast of each haddock whole.
Sprinkle salt over the haddocks and let them rest on a clean board for a few hours, then wipe off the salt.
Cut off the heads and fins of the haddocks.
Carefully remove the skin from the haddocks.
If the haddocks are small, cut them in half; if large, cut them into thirds.
Make the sauce
In a pan, brown the minced onion in butter.
Dust the browned onion with flour.
Pour in the beef soup and let it boil briefly.
Cook and serve
Place the haddocks in a fish drainer, then boil them in salted water with a splash of vinegar until cooked.
Carefully remove the haddocks, place them on a dish, and pour the sauce over them.
Optionally, add white wine, mushroom ketchup, and oysters before serving, garnished with lemon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haddock
- Forms the main body of the dish, cooking to a flaky texture.
- Butter
- Adds fat and richness, and helps brown the onion for flavour.
- Flour
- Thickens the sauce as it is cooked with the onion and fat.
- Beef soup
- Forms the liquid base of the brown sauce, adding savoury flavour.
- Onion
- Adds aromatic sweetness and savoury depth when browned.
The step that matters
Boiling the haddocks. Fish cooks quickly and becomes dry and tough if overcooked, so it should be removed as soon as it is opaque and flakes easily.
Swap the onion
How well each one fits the dish's main ingredients (haddock, butter, flour, beef, vinegar, white wine, mushroom):
- Shallotfits better

- Potatofits about as well
Fit is the average pairing score against haddock, butter, flour, beef, vinegar, white wine, mushroom. Candidates are from the same food group and used in at least 100 recipes.
