How do I keep my bottom pie crust from getting soggy?
Make sure that the filling isn't too wet, as a liquidy filling will make the pastry go soggy. You can also use a ceramic pie bird to vent additional steam from the pie, creating a crisper bottom crust. Make sure to bake the pie in a metal dish on a metal cookie sheet, too, as metal conducts heat better in the oven and will make for crispier pastry.
