Almond flour makes a most delicious and fragrant gluten-free tart crust. I have long been a devotee to the buttery cookie crust. Still am, really, but I heard somewhere from someone it is good to diversify and I'm pretty sure they were talking about cheesecake.  Even when gluten intolerance is not an issue, I love to make this crust because it is super yummy and also because I can rationalize that by eating 2 or 3 of these tarts I am loading up on heart-healthy monounsaturated fats and antioxidants and other nutrients from the almonds. ;)
