Arrowroot is a large perennial herb (Maranta arundinacea) found in rainforest habitats. The herb is cultivated for a starch obtained from the rhizomes (rootstock), which is also called arrowroot. It is a thickening agent that may be used as a one-for-one replacement for cornstarch. As a thickener, it can be used for soups, sauces, and puddings. It has no flavor on its own and is the easiest starch to digest. It is also an excellent ingredient for gluten free baking or breading and creates a softer and lighter texture to cakes and breads. Our Arrowroot Starch is not irradiated and contains no added sulfites. (from Bob's Red Mill)
