Blind-baking

Baking blind (sometimes called pre-baking) is the process of baking a pie crust or other pastry without the filling. Blind baking a pie crust is necessary when it will be filled with an unbaked filling (such as with pudding or cream pies), in which case the crust must be fully baked. It is also called for if the filling has a shorter bake time than the crust, in which case the crust is partly baked. Blind baking is also used to keep pie crust from becoming soggy due to a wet filling.
