White rice flour is produced from rice that has had the bran and germ removed. Then the rice is ground into a fine powder.
White rice flour is one of the least allergenic flours to use for baking for anyone following a gluten-free diet. White rice is also easier to digest and assimilate than other grains. White rice flour is the backbone of my gluten-free flour mix. It has a neutral, mild taste which does not alter the taste of your baked goods.
If you are using Authentic Foods Brand White Rice Flour and their sweet rice flour or the new Vitacost White Rice Flour you do not even need to add any bean flour to your recipes.
You can find Authentic Foods Brand White Rice Flour on Amazon or through Vitacost. Vitacost often has terrific sales on their gluten-free products and it's a great time to save some money and stock up on these flours.
