Why is pie shell often baked on top of an upside down pan?

Pie shells are not typically baked on top of an upside-down pan. They are usually baked in a regular pie pan, either on a baking sheet or directly on the rack in the oven.

Here's why pie shells are baked in a pie pan:

* Structure: The pie pan provides the necessary shape and support for the crust to hold its form while baking.

* Even Heating: The pan allows for even heat distribution, ensuring the crust cooks evenly without burning.

* Ease of Filling: The pan makes it convenient to fill the shell with the pie filling.

Possible Reasons for Confusion:

* Blind Baking: Pie shells are sometimes blind baked (baked without filling) to prevent sogginess. This often involves placing pie weights on top of the crust to prevent it from puffing up. The weight is usually placed on parchment paper or aluminum foil, not directly on the crust.

* Upside-Down Cakes: Some cakes, such as upside-down pineapple cake, are baked with the fruit on the bottom of the pan. This is not related to pie shells.
