Dissolve one tablespoon of butter and combine with two tablespoons of all-purpose flour, 1 cup of hot milk, salt, and pepper. Let it thicken over low heat. Strain this sauce through a sieve and mix with pre-cooked or baked fish pieces. Prepare a casserole with 10 cooked potatoes, mixed with two egg yolks and one tablespoon of butter. Place the casserole around a plate, having the fish mixture in the center, topped with the sauce. Dust the casserole with a little grated breadcrumbs, covered with some melted butter. Bake it.
