Roll out some puff paste an inch thick, cut with a patty-cutter as many rounds as are needed, then with a smaller cutter stamp each round about half an inch deep. Bake in a quick oven; when done lift the centers out carefully with a knife, remove a little of the inside. When wanted heat the patty shells and fill with spaghettina in tomato sauce, mushrooms or vegetables in a cream or savory sauce, or the filling as given for spinach border mould. A few truffles cut fine are a nice addition to tomato sauce. Lay the little tops on and serve.
