You might be wondering what "milk pie" is, but when I heard the waitress mention it, I perked right up. Having grown up in central Pennsylvania, I am plenty familiar with the delights of Amish pastries (shoo-fly pie, anyone?). My Grandma Laudig always made us milk pie with the leftover pie crust dough. It's the simplest thing in the world, really -- a little flour, a little sugar, a little cinnamon, some milk, and a tiny dab of butter to make a creamy filling.
