The crust will get a little darker as it baked, once filled. If it's getting too dark, you can either 1) Drape a sheet of foil lightly over the entire pie (making sure it's not touching the top of the pie filling, 2) Fashion pieces of
foil over just the crust while the pie is baking, or 3) Use a
pie shield.
To make this gluten-free, you can use the
Pretzel Pie Crust (using gluten-free pretzels) and cornstarch in place of the flour in the filling.
The pie dough can be made in advance and either refrigerated for up to two days (either unrolled or rolled and fitted into the pan), or frozen (either unrolled of rolled and fitted in the pan) for up to two months. Once baked, the pie can be kept at room temperature (or refrigerated) for up to 5 days.
