We say one day. If you make it farther ahead than that, your crust will get soggy. Leftover pie is one thing but if you’re presenting this gorgeous dessert as a lovely and fresh offering, you want it to taste as good as possible. If you’re really budgeting your time, make the dough ahead of time and put it in the freezer. Thaw and make the pie the day before Thanksgiving.  [art]Workman[/art]
