Beat the eggs well, and then, when very light, add the milk. Add sugar and mix thoroughly. Spread the bottom of the pan with the raisins, and then put a layer of diced Bread over them. Sprinkle this with raisins, and continue adding the Bread and raisins alternately till all are used. Add a little Essence of Lemon or Vanilla to the egg mixture, and pour all this over the Bread. Set in the oven and bake for an hour. Serve with a Hard or Lemon Sauce. Some add a little Sherry Wine, according to taste and the methods of the family.
