To Dress Haddocks with Brown Sauce

Ingredients

Directions

Prepare the haddock

  1. Gut and clean the haddocks, then wipe them with a cloth.

  2. Keep the breast of each haddock whole.

  3. Sprinkle salt over the haddocks and let them rest on a clean board for a few hours, then wipe off the salt.

  4. Cut off the heads and fins of the haddocks.

  5. Carefully remove the skin from the haddocks.

  6. If the haddocks are small, cut them in half; if large, cut them into thirds.

Make the sauce

  1. In a pan, brown the minced onion in butter.

  2. Dust the browned onion with flour.

  3. Pour in the beef soup and let it boil briefly.

Cook and serve

  1. Place the haddocks in a fish drainer, then boil them in salted water with a splash of vinegar until cooked.

  2. Carefully remove the haddocks, place them on a dish, and pour the sauce over them.

  3. 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.
