Butterscotch Banana Pie - PCOS-Friendly Recipe

In a bowl with a pastry blender or in a food processor blend or pulse together flour, butter, shortening, and salt until mixture resembles coarse meal. Add 2 tablespoons ice water and toss with a fork or pulse until water is incorporated. Add enough remaining ice water, 1 tablespoon at a time, tossing or pulsing to incorporate, until mixture begins to form a dough. On a work surface smear dough in 3 or 4 forward motions with heel of hand to slightly develop gluten in flour and make dough easier to work with. Form dough into a ball and flatten to form a disk. Chill dough, wrapped in plastic wrap, 1 hour. Makes enough dough for a single-crust 9- to 10-inch pie.
