Coarsely ground almond meal creates a crust similar in texture to a graham cracker crust. This recipe is best suited to a filling that does not require baking as nut-based crusts don’t fare as well when baked for extended periods of time. If you wish to try, cover the edges with a crust protector (a homemade foil version will do) to prevent over-browning and start out with a well-greased pie plate.
