My sister made this yummy pie for us this weekend while she and her family were up for a visit. It might be the best rhubarb pie I’ve ever had. Feel free to use any pie crust recipe you wish, or you can select a nice prepared pie shell. 5b’s Gluten Free Pie Crust is very good – you can find it in our freezer section. Or… use Anna’s favorite pie crust recipe found at end of this post.
