Chocolate Cream Pie
1 cup sugar
3 tablespoons cornstarch
6 tablespoons unsweetened cocoa
1/4 teaspoon salt
2 cups milk
3 slightly beaten egg yolks
3 tablespoons butter
1 teaspoon vanilla extract
1 (9-inch) baked pastry shell
In a double boiler, combine sugar, cornstarch, cocoa, and salt; gradually stir in milk. Cook and stir over medium heat until mixture boils and thickens. Cook 2 minutes longer. Remove from heat.
Stir a small amount of hot mixture into egg yolks; return to hot mixture; cook 2 minutes, stirring constantly. Remove from heat. Add butter and vanilla; cool to room temperature. To prevent a crust from forming, put clear plastic wrap directly on top, touching surface of the hot pudding to the sides of the bowl. When cooled, pour into baked pastry shell.
Beat 3 egg whites with 1/4 teaspoon cream of tartar and 1/2 teaspoon vanilla until soft peaks form. Gradually add 6 tablespoons sugar, beating until stiff peaks form and all sugar is dissolved. Spread atop pie, sealing to pastry. Bake in moderate oven, 350 degrees F, about 12 to 15 minutes, or until meringue is golden. Cool.
I started by baking a single crust pie shell using My Mother's Pie Crust recipe.
It is best to cook cream pies like this in a double boiler because it is very easy to scorch the milk and sugar mixture.
Stir some of the chocolate mixture into the egg yolks before adding them to the hot mixture.
