Sweet Rice Flour is made from glutinous rice (it does not contain the gluten fraction that is prohibited to the gluten intolerant). Often used as a thickening agent. Sweet rice flour is becoming more common in gluten-free baking for tender pies and cakes. It has the ability to smooth the gritty taste (that is common in gluten-free baked goods) when combined with other flours, see Multi Blend recipe.
