Basic Cream Pie
2 C. milk
1/2 cube margarine (I use regular butter)
2 eggs
1/2 tsp. vanilla
3/4 C. sugar
4 well-rounded tbsp. cornstarch
Put milk in a double boiler, add margarine and bring to just about boiling. Beat eggs, vanilla, sugar
and cornstarch in a seperate bowl. Then stir into the hot mixture and stir till thickened(I turn off the heat to do this.) Pour into a pre-baked pie crust or a graham cracker crust and put in refrigerator.
Variations:
Coconut pie- fold in 1 to 1 1/2 C. coconut and put toasted coconut on top
Chocolate pie - fold in approx. 3/4 C. chocolate chips to hot pudding
Banana pie - fold in chunks of banana
