Just before serving, rub the outside of the filled pie plate with a warm, damp towel. This softens the butter in the crust, making it less likely to stick to the pie plate.

To prepare the towel, rinse it in very hot water, then wring it well.

This procedure is not necessary for crumbs crust that have been baked, since they slide out easily.
