Directions

Prepare the head

  1. Wash the cod's head thoroughly and score it with a knife.

  2. Sprinkle a little coarse sea salt on it.

  2. Dust it with flour and baste with butter.

  3. After some time, turn the head, season, and baste the other side.

  4. Turn it often and baste frequently, adding bread crumbs.

  5. Roast for four to five hours if large.

Make the sauce

  2. Mix well with the butter and the beaten yolks of eggs.

  3. Strain the mixture through a sieve and return to the saucepan.

  4. Add shrimps or pickled cockles, red wine, and lemon juice, simmer for a minute or two.

  5. Pour the sauce into the pan where the head was roasted and stir well.

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

What each ingredient does

Eggs
Yolks bind the sauce and thicken it as they heat, giving it a smooth, rich body.
Butter
Adds fat and richness, carrying flavour and helping the head brown while roasting.
Bread crumbs
Absorb juices and fat during roasting, adding body and a slightly crisp, browned crust.
Lemon juice
Adds acidity that brightens the rich butter and egg sauce and balances its richness.
Liver of the fish
Adds rich, savoury depth and body to the sauce.

The step that matters

Stirring the egg yolks into the sauce. Egg yolks thicken when heated gently; if the sauce gets too hot or boils hard after they are added, the yolks can scramble and turn grainy. Straining and stirring keep it smooth.

Fit is the average pairing score against butter, nutmeg, mace, bread, egg, anchovy, liver. 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).
