Topping:
Preheat oven to 350°F.
Lay fish fillets in a shallow pan. Season with the salt, pepper, paprika, and lemon juice. Make sauce of butter, salt and pepper, flour, dry mustard, and milk, cooking in a saucepan over a low heat, stirring constantly until thickened. Pour this sauce over seasoned fish. Top with buttered crumbs. Bake for 35 minutes.
Serves 6.
