Gluten-Free Deep Dish Apple Pie

I first developed this gluten-free and egg-free pie crust for my Nourishing Meals cookbook, and it has remained a favorite ever since. The deep-dish apple pie it supports is one of those classic, crowd-pleasing recipes that feels comforting and familiar while still being accessible for many different dietary needs. The secret to its tender, flaky texture lies in using the superfine flours listed below—these are ground much more finely than standard gluten-free flours. I like the ones from Authentic Foods, which you can order online or sometimes find at local health food stores.
