2-1/2 c. milk 1 c. sugar 2/3 c. flour 1/8 tsp. salt 1-1/2 sq. bitter chocolate 1 egg 1/2 tsp. vanilla
Heat the milk to scalding in a double boiler.
Mix the sugar, flour, and salt and add to the milk. Cook over the flame until the flour has thickened. Return to the double boiler and cook for 10 or 15 minutes longer. Melt the chocolate over hot water and add to the mixture. Beat the egg and add slowly to the mixture, remove from the fire, and add the vanilla. Pour into a baked pie crust, cover with meringue, if desired, and bake in a moderate oven for 10 to 15 minutes. If the meringue is omitted, cool and cover with whipped cream just before serving.
