This pie has no wheat in the crust. I've made some terrible-tasting gluten-free pie crusts. This one isn't bad. Especially if you pile ice cream on top. Here's the recipe in case you really like someone a whole lot who's allergic to wheat.
p.s. I didn't have tapioca flour or potato starch flour or margarine or butter-flavored Crisco or sweet rice flour, or Guar gum. So I improvised using gluten-free all purpose baking flour, butter, regular Crisco, organic brown rice flour, and Xanthan gum.
