4 1/4 c. milk
1/3 c. sugar
2 tbsp. flour
2 tbsp. butter
2 tbsp. cornstarch
1/2 tsp. salt
6 eggs
1 tsp. vanilla

Combine just 4 cups milk and sugar and heat slowly until boiling. Add butter. Mix flour, cornstarch, salt, yolks of eggs and 1/4 cup milk until the mixture is smooth. Slowly add egg mixture to milk and simmer for 5 minutes.

Beat egg whites with clean beaters until stiff. Fold into hot milk mixture. This is not easy, and sometimes requires quite intense beating/folding.

Slowly boil for 5 minutes. Add vanilla. Pour into cooked pie crust or graham cracker pie shell. Cool for 1 hour before serving.
