Final answer:
It is generally false that two-crust pies can be successfully baked in a microwave oven due to the moist cooking conditions of microwaves, which hinder the crisping of the crust.
Step-by-step explanation:
Two-crust pies can typically be baked in a conventional oven where the crust can become flaky and golden due to the dry heat. While it is technically possible to bake a pie in a microwave oven, the results are often less successful than with conventional baking.
Microwaves cook by agitating water molecules, which leads to moist cooking conditions. This environment is not ideal for achieving a crispy pie crust. Therefore, it is generally false that two-crust pies can be successfully baked in a microwave oven.
