Salt Mackerel with Cream Sauce

Ingredients

Directions

Prepare the fish

  1. Soak the mackerel overnight in lukewarm water, changing it in the morning for ice-cold water.

  2. Remove all the salt and wipe the fish dry.

Cook the fish

  1. Grease a grill with butter and rub the fish on both sides with melted butter.

  2. Broil the fish quickly over a clear fire, turning gently to avoid breaking it.

  3. Place the fish on a hot dish and cover while preparing the sauce.

Make the sauce

  1. Heat the milk until scalding.

  2. Stir in the cornstarch mixed with a little water until thickened.

  3. Add the butter, pepper, salt, and chopped parsley to the thickened mixture.

  4. Beat the egg lightly and incorporate it into the sauce.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Salt mackerel
The main fish, whose salting is undone by soaking so it becomes mild enough to eat.
Cornstarch
Thickens the milk into a smooth, pourable cream sauce as it heats.
Egg
Adds richness and body to the sauce when beaten in.
Butter
Adds fat and flavour to the fish and the sauce, and helps the fish brown on the grill.
Milk
Forms the liquid base of the cream sauce.

The step that matters

Beat the egg lightly and incorporate it into the sauce. Egg proteins set with heat, so if the sauce is too hot when the egg goes in, it can curdle or turn grainy instead of staying smooth and creamy.

Swap the parsley

How well each one fits the dish's main ingredients (milk, butter, pepper, egg):

  1. Nutmegfits about as well
  2. Parsleythe original
  3. Cinnamonfits about as well
  4. Tarragonfits less well

Fit is the average pairing score against milk, butter, pepper, egg. Candidates are from the same food group and used in at least 100 recipes.
