Chocolate Sponge Pie Recipe

1 c Sugar
1/3 c Flour
1/4 ts Salt
1/2 c Ground chocolate
3 Eggs; seperated
1 c Milk
9 Inch unbaked pastry shell

Sift together sugar, flour, salt, and chocolate.
Beat egg yolks well and mix with milk; combine with dry ingredients.
Beat egg whites stiff and fold into chocolate mixture, mixing well.
Pour into pie shell. Bake in a hot oven (450ø) for 10 minutes, then reduce the heat to moderate (350ø) and bake until firm.
Test by inserting a knife blade; when it comes out clean, the chocolate sponge is done.

Serve cold with whipped cream or ice cream.
