Underbaked bottom crusts or crusts that have soaked up moisture from the filling are a common fault in pies. Soggy bottoms can be avoided in several ways:
- Use mealy dough for bottom crusts. Mealy dough absorbs less liquid than flaky dough does.
- 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.
- For fruit pies, line the bottom of the pie shell with a thin layer of cake crumbs before pouring in the filling. This helps absorb some juice that might otherwise soak into the crust.
- Use dark metal pie tins, which absorb heat. (Because so many bakers use disposable aluminum pans, other methods must be relied on. Disposable pans with black bottoms are sometimes available.)
- If finished pies still have underbaked bottoms, they can be set on a flattop range for a few minutes. However, exercise extreme care to avoid scorching.
