Use in sauces and soups. To your good health. Ground from 100% dehydrated whole potatoes, our all-natural Potato Flour is perfect for thickening sauces, soups, and gravies. A teaspoon or so added to your baked goods lends a moist crust, so it is especially useful in gluten-free baking. Gluten free. You can see our quality! Bob's Red Mill products labeled gluten free are batch tested in our quality control laboratory. We use an ELISA Gluten Assay test to determine if a product is gluten free. All natural.
