Take a slice one and a half inches thick and well trimmed. Cut in two or three pieces horizontally. Trim a little, by paring off the corners, to make each piece round. Season with salt and pepper as desired. Butter the paper bag well, also the fillet of beef. Add garnishing - as, for example, from four ounces to eight ounces of either mushrooms, tomatoes, artichoke bottoms, olives, a little anchovy, cooked and sieved spinach, or any other kind fancy may suggest. Place round the fillet; add one or two tablespoonfuls of any kind of sauce (this is purely a matter of taste). Put on grid. Allow ten to fifteen minutes in very hot oven (350 Fahr.).
