Thanksgiving Special: The Design of Pie Tins
I don’t bake very often so this might be commonplace, but I found these pie crust tins to be pretty nifty.

When you purchase the crust, it is lined by a solid piece of plastic. It is removed by crimping up the edges of the tin.

After the pie is finished, the plastic piece is inverted and placed on top, now functioning as a cover if the pie is stored. Nice.
