1/2 c. butter melted in 1 c. boiling water

Stir in 1 cup flour and take from stove and when cool enough to not burn the fingers when pressed into it, beat in, 1 at a time, 3 eggs without previously beating them. Then drop the batter quickly in spoonfuls on buttered tins, leaving plenty of room to rise. Bake in moderate oven until well browned, about 25 or 30 minutes. When nearly cooled, cut a small hole in top of each puff and pour in the following filling.

FILLING:

1/2 pt. of milk in double boiler
1 egg
3 tsp. sugar
2 tsp. flour

Beat egg and sugar and flour together. Pour hot milk over this mixture, stirring all the time and return to the stove to cook until it thickens. Cool and flavor with lemon or vanilla and fill each puff.
