Chocolate Cream Pie

3 squares Baker’s Unsweetened Chocolate

2½ cups milk

1 cup sugar

6 tablespoons flour

½ teaspoon salt

2 egg yolks, slightly beaten

2 tablespoons butter

1 teaspoon vanilla

1 baked 9-inch pie shell

2 egg whites

4 tablespoons sugar

Add chocolate to milk and heat in double boiler. When chocolate is melted, beat with rotary egg beater until blended. Combine sugar, flour, and salt; add gradually to chocolate mixture and cook until thickened, stirring constantly; then continue cooking 10 minutes, stirring occasionally. Pour small amount of mixture over egg yolks, stirring vigorously; return to double boiler and cook 2 minutes longer. Remove from boiling water; add butter and vanilla. Cool. Turn into pie shell. Beat egg whites until foamy; add sugar, 2 tablespoons at a time, beating after each addition until sugar is blended. Then continue beating until mixture will stand in peaks. Pile lightly on filling. Bake in moderate oven (350°F.) 15 minutes.
