Cream Mackerel

Preparation:

Preparation: Clean the mackerels, wash them, dry them, arrange them in a baking dish so that everyone has their own space. In a bowl, mix the cream with the mustard, add the lemon juice passed through a sieve and a little chopped parsley. Lightly salt the fish because the mustard already has a strong taste. Pour the cream mixture over the mackerel, spread a few flakes of very fresh butter. Place the dish in the preheated oven and cook over moderate heat for about half an hour. With the heat, the sauce will become a little thicker and the surface will have a gratin appearance. Serve in the same container.
