This small container of cornstarch makes it easy to keep some on hand in my pantry. You can keep it filled with cornstarch you buy in bulk from nuts.com or elsewhere.
Tapioca starch (or tapioca flour) is the starch extracted from the cassava root. It is not considered a grain, and is useful in gluten free as well as Paleo baking. It adds crispness and chew to baked goods.
Potato starch adds lightness to gluten free baking, as well as structure. It's made from peeled potatoes, and has no potato flavor. It is not the same as potato flour.
The only truly superfine white rice flour available. If you are tired of gritty GF baked goods, this is the rice flour you need for all my all purpose GF flour blends.
This is my pick for the best ready-made all purpose gluten free flour blend. It's the most versatile blend, and works in all of my recipes that call for an all purpose gluten free flour.
