In a medium-sized bowl, mix almond flour, arrowroo,t and salt. Stir in the coconut oil and syrup while mixing with a rubber spoon or spatula. The mixture should be crumbly but stick together when pressed between your fingers. Add a tablespoon of water if needed.
Form into a ball and press into a pie dish greased with coconut oil. Alternatively, follow the directions above and roll out onto wax paper with a rolling pin until approximately 1/8 inch thick.
Make prick marks with a fork along the bottom. Place the crust in the freezer for 5 minutes.
Bake according to the pie recipe instructions. This crust does not need to be prebaked. If using a wet filling like pumpkin, pre-bake with weights for approximately 10 mins at 350. If using for a custard or cream, bake completely for approx 15 mins.
