Notes
Storage:Leftover sweet potato icebox pie will keep for four to five days in the refrigerator tightly covered. Freeze leftovers for up to 3 months. Wrap the pie tightly with plastic (pressed against the top and sides) and cover that with a layer of foil.Always let icebox pies like this one thaw in the refrigerator. Even using the defrost setting on the microwave will cause the delicate filling to split or melt.Tips:
Before freezing, use a knife to slide a piece of parchment paper between slices. Then, you can pull out an individual piece from the freezer to enjoy without needing to thaw the whole thing.
One cup of sweet potato puree is about one large sweet potato or two smaller ones.
