Banana Cream Pie

Mix cornstarch, sugar and salt and add gradually to cold milk in saucepan.  Stir constantly over medium heat until mixture is thick and bubbles, 4 to 5 minutes.  Beat eggs slightly and add part of hot mixture with a whisk.  Blend and return to saucepan.  Cook, stirring constantly, for 2 minutes.  Remove from heat and blend in butter.  Add Vanilla and Banana extract.  Cool.  Slice 4 bananas and arrange them in your baked pie crust on the bottom.  Pour mixture on top of bananas.   Chill and then topped with whipped cream or a meringue as desired.
