To Fry Haddocks in Sauce

Ingredients

Directions

Prepare the fish

  1. Skin and remove the heads from the haddocks.

Make the sauce

  1. In a frying pan, melt the butter and stir in the flour until browned.

  2. Add the minced onions, pepper, and salt to the browned butter.

  3. Pour in enough boiling water to nearly cover the fish pieces and bring to a boil.

Cook and serve

  1. Add the fish to the pan.

  2. Cook until one side is done, then turn the fish and cook the other side.

  3. Serve hot.

  4. Pour the sauce over the fish.

  5. Garnish with parsley.

  6. If desired, omit the onions and substitute with mushroom catsup and lemon pickle.

What each ingredient does

Haddock
Forms the main body of the dish and cooks to a flaky texture.
Butter
Provides fat for frying and, when browned, adds a nutty flavour to the sauce.
Flour
Thickens the butter into a roux that gives the sauce body.
Onions
Add savoury sweetness and aroma to the sauce as they cook.

The step that matters

Browning the flour in the butter. Cooking the butter and flour together until browned builds a roux with nutty flavour and thickening power. Stopping too early leaves a raw floury taste, while going too far scorches it and makes the sauce bitter.
