When it comes to baking, it can be challenging to find gluten-free alternatives for your favorite recipes. If you need a gluten-free option when making pies, this almond flour pie crust is an excellent choice. This recipe is entirely grain-free because almond flour isn't a type of milled flour, rather it is simply finely ground almonds. Both almond flour and almond meal are made from ground almonds, but there are two subtle differences of note. Almond flour is made from blanched almonds where the skins have been removed. It also is ground more finely than products labeled almond meal. Almond meal has a more coarse grind and you will notice dark flecks in the product because the almond skins were not removed. Almond "Flour" Is readily available in grocery stores in the baking aisle or gluten-free sections. However, it can sometimes be pricey, and making your own almond flour at home is easy: place whole blanched almonds, about 1/4 cup at a time, in the food processor. Pulse until a flour-like consistency is achieved. Use a sifter to separate any larger pieces that remain and repeat until all of the almonds are transformed into flour. Whether store bought or homemade, almond flour should be stored in an airtight container in the refrigerator. Since an almond flour pie crust doesn't contain any gluten, it cannot be rolled and shaped in the same ways as a traditional flour-based pastry crust. This crust is easy because instead of rolling it out and transferring to the pie pan, it is simply pressed into the pan. If you want to decorate the rim of the pie crust, using a fork and pressing it into the top edge works best.
