This no-sugar-added apple pie gets its natural sweetness from antioxidant- and fiber-rich dates. Cider vinegar helps to enhance the flavor. We like Gala apples for their sweetness and crisp texture, but any sweet, firm apple will work well. If you like your apple pie on the tart side, add a Granny Smith to the mix. We use frozen pie crusts for the bottom and top of the pie. The dough should release easily from the tin for the top crust within about 10 minutes out of the freezer. If not, let it sit out a bit longer until it releases easily.
