maybe it depends on the brand of gf ginger snaps. the crust wicked moisture from the pie. Gritty. Unpleasant "raw" sensation.
Gluten-Free Pumpkin Cheesecake with Gingersnap-Walnut Crust
From EatingWell: November/December 2011
We pulled out a few of our favorite EatingWell tricks to achieve plenty of creaminess in our pumpkin cheesecake without all the saturated fat of a typical recipe: nutrient-packed canned pumpkin and pureed nonfat cottage cheese replace some of the cream cheese. A touch of pumpkin pie spice warms up the flavor. For the crust, shop the natural-foods section for gluten-free gingersnaps without any hydrogenated oil. Simple toasted walnuts are an elegant garnish. Or try making candied walnuts. Just be careful not to eat all of them before they make it to the cake!
