A common pie fault is an underbaked bottom crust or a crust that soaks up moisture from the filling. Soggy bottoms can be avoided in several ways:
- Use mealy dough for bottom crusts. Mealy dough absorbs less liquid than flaky dough.
- Use high bottom heat, at least at the beginning of baking, to set the crust quickly. Bake the pies at the bottom of the oven.
- Do not add hot fillings to unbaked crusts.
- Use dark metal pie tins, which absorb heat. (If you use disposable aluminum pans, choose pans with the bottoms colored black.)
