What is the history behind the creation of Montgomery Pie and how is it traditionally made?

Montgomery Pie is a traditional dessert that originated in Montgomery County, Pennsylvania. It is believed to have been created by the Amish community in the area. The pie is typically made with a layer of lemon custard on the bottom and a layer of chocolate custard on top, all enclosed in a flaky pie crust. The pie is baked until the custards set and the crust is golden brown. It is often served chilled with a dollop of whipped cream on top.
