Boil roes in water with a little vinegar for ten minutes. Plunge into cold water; wipe the roe dry. Mash the yolks into melted butter, anchovy paste, parsley, lemon juice, salt and pepper to taste. Add bread crumbs and then mix in lightly the roe that has been broken into pieces. Put all in baking dish, cover with bread crumbs and flakes of butter, and brown in oven.
