* An Employee-Owned Company * To Your Good Health... Bob Moore * Gluten Free * Also Known As Tapioca Starch * Kosher Pareve * Wholesome Tapioca Flour, also known as tapioca starch, is ground to powdery fine granulation from the dried roots of the cassava plant. It is a starchy and slightly sweet flour that is especially good for thickening soups, sauces, dips, pie fillings and puddings. Tapioca Flour is also an excellent ingredient for gluten-free baking, as it lends a springy texture, promotes browning and makes crispy crusts. You Can See Our Quality!
