Erawan Tapioca Starch is a kind of gluten free starch that was extracted from Cassava roots. It is widely used in Asian cooking, particularly in Thai cuisine. With its extremely smooth texture, it is widely used as a thickener for sauces and gravies. It is also common to be used in combination with other flours like rice flour to enhance the silkiness and pliability of dough, especially for gluten free recipes.
