Ingredients 4 cups superfine brown-rice flour ⅔ cup tapioca flour or starch 1 ⅓ cups potato starch Directions To measure brown-rice flour and tapioca flour, use a large spoon to scoop flour into a measuring cup, then level it off with the back of a knife. Do not use the measuring cup itself to scoop your flour when measuring; it will compact the flour and you will have too much for the recipe. Add both flours to a large resealable plastic bag, along with potato starch; reseal and shake until well combined. Rate it Print
