Tapioca Flour is a staple in your gluten free pantry.
It is a wonderful sauce and gravy thickener without the worry of using a wheat product or corn product.
When making your own blend of an all purpose flour blend, tapioca flour adds just the right amount of "lightness" so your flour blend isn't too heavy (and therefore won't cause tummy troubles). There are many of these recipes on line. Its a great replacement for both corn starch and potato starch!
*Please note that tapioca starch IS the same as tapioca flour.
