Will freeze in a sealed plastic bag for up to 3 months.
ADDITION (Jan. 27/10): I made these again today, using 1 cup of brown rice flour, 1/3 cup potato starch, 1/3 cup tapioca starch, and 1/3 cup oat flour. I also added about 1/2 tsp of garlic powder and 3/4 tsp Italian seasoning. They were FANTASTIC!! So quick to make, and so great fresh. Definitely give them a try, just be sure to roll them as thin as possible!
