Before Cool Whip and instant pudding, this was how a cream pie was made.
Cream pie are often associated with comedians who use them as a gimmick
3 cups whole milk
3/4 cup white sugar
1/3 cup all-purpose flour
1/4 teaspoon salt
3 egg yolks, slightly beaten
2 tablespoons butter
1 teaspoon vanilla
2 In a large saucepan, scald the milk.
4 Over medium heat, stirring constantly, cook until thickened.
5 Cover and, stirring occasionally, cook for two minutes longer.
6 In a small bowl, have the 3 egg yolks, slightly beaten, ready; stir a small amount of the hot mixture into beaten yolks; when thoroughly combined, stir yolks into hot mixture.
7 Cook for one minute longer, stirring constantly.
8 Remove from heat and blend in the butter and vanilla.
9 Let sit until lukewarm.
10 When ready to pour, slice bananas and scatter in pie shell; pour warm mixture over bananas.
11 If desired, make a meringue (you’ll have 3 leftover egg whites) to top the pie, or just let the pie cool until serving.
