what a wonderful idea. I have always put aside a day for pie baking in the fall.I love your idea on freezing the ingredients in a pie plate then wrapping and stacking.
I have taken prepared pie crusts,filled them and wrapped tight.pop them in the freezer. takes up a little more room but when baked the pie crust is always great.
I will try your suggestion.sure saves room in the freezer when you are prepping for the holidays.
Thank you
