Every apple season I make 12 pies and put them in the freezer so we can eat an apple pie every month for the whole year. This is the recipe I use that freezes and reheats the best. I've found that the tapioca as a thickener freezes well but flour thickened pies don't freeze and reheat very good. Sometimes I use cheap pie tins and just freeze the pies in those. Other times I freeze them in my glass pie plates and then pop them out and stack the frozen pie disks in the freezer. Whatever works best for you.
