Take half a pint of white sauce, made with an ounce of flour, an ounce of butter, and half a pint of milk, and flavored with a little mace. Add to it two large thinly-sliced onions cooked in a little butter in a bag, and from four to six halved hard-boiled eggs. Pour gently into a well-greased double bag and make very hot in the oven for ten minutes. Dish up on a hot dish and serve as quickly as possible. (350 Fahr.)
