Preheat oven to 400 degrees.
In a large mixing bowl, combine flour and shortening. Cut shortening into flour until the mixture is crumbly.
Add in eggs and milk and mix until doughy. Break dough into two (save second for another pie), and chill for 20 minutes.
Roll one of the balls of dough out to fit the bottom and sides of a 15x10 baking sheet.
Mix all the ingredients for the filling. Pour into the pie shell.
Bake at 400 degrees for 15 minutes and then reduce the heat to 350 and bake for another 25-30 minutes or until nicely golden.
