Prepare the pastry and line a pie plate with it, then rub with butter as directed in the custard pie. Now cover the bottom thickly with sliced peaches and then prepare the custard as follows: Place sugar, milk, egg yolks, egg and cinnamon in a mixing bowl. Beat to thoroughly mix and just before pouring the custard over the peaches dust them well with sifted flour. Pour on the custard and bake in a slow oven until firm. Use whites of eggs for meringue. Raspberries and plums may be used in place of the peaches for variety. When making these pies, always use the regulation custard pie tin, the ones with the straight sides.
