I tried making pie crust from scratch about 3 times – no good and one from a mix, again, no good. But I did buy some frozen from Whole Foods that are great. First ingredient is butter. No PUFAs. Other ingredients include: rice flour, tapioca starch, corn starch, eggs, potato starch, water, lemon juice, baking powder, xanthum gum and cane juice. I made a sour cream rhubarb pie with it for my book club – everyone thought the whole pie was great and couldn’t tell that the crust was GF.
