Notes
To freeze: Pie crust will keep in the freezer for up to 6 months. You can freeze it in disc form wrapped in plastic wrap and sealed in a freezer bag, or you can roll the crust out on a generously floured piece of parchment paper, roll up, and place in a freezer bag. Discs will need to be thawed in the fridge for 12-24 hours, rolled out dough can be thawed on the counter for 15 minutes before using.
