Mackerel, Fillets of

Ingredients

Directions

Prepare the fish

  1. Wash, dry, and fillet the mackerel.

  2. Melt the butter in a sauté pan and fry the fillets without browning them.

  3. Remove the fish and keep it warm.

Make the sauce and serve

  1. Add the Bechamel sauce to the pan and heat nearly to boiling.

  2. Return the fish to the pan, cover closely, and simmer gently for 10 minutes.

  3. Carefully transfer the fish to a warm dish, add lemon juice to the sauce, season if necessary, and strain the sauce over the fish.

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

What each ingredient does

Mackerel
Forms the main body of the dish and provides its rich, oily flavour.
Bechamel sauce
Provides a creamy, smooth coating that moistens the fish as it heats.
Butter
Adds fat for gentle frying and a rich, savoury flavour to the fillets.
Lemon juice
Adds acidity that brightens the rich sauce and balances the oily fish.

The step that matters

Simmer the fish gently in covered pan. Fish protein sets and toughens quickly at high heat, so a gentle simmer under a lid keeps the fillets moist and tender. Boiling the sauce hard can also cause it to separate or form a skin.
