This all-purpose buttery, flaky gluten-free low FODMAP pie crust can be used for savory dishes, like quiche, as well as sweet pies; just use the optional sugar or not. I do recommend that you do use a low FODMAP flour blend that contains xanthan gum for best results. Xanthan is low FODMAP and without it, your low FODMAP pastry will not be very workable or easy to roll (if even at all possible) and the finished product will lack flakiness.
This gluten free pie crust makes enough for a double-crusted pie. You can halve this low FODMAP recipe for a single crust.
Makes enough for a 9-inch (23 cm), double crust pie or two crusts for single-crusted pies.
