Arrowroot is an easily digested starch extracted from the roots of the arrowroot plant, Maranta arundinacea. The plant is native to the tropics of South America, where it has a long history of cultivation by native peoples.
Arrowroot, or arrowroot starch, is a powdery product made from the arrowroot plant, a starchy tropical root. The plant is dried and ground up to make the powder, which is primarily used as a thickener in the kitchen, much like cornstarch. Much like cornstarch, it is an excellent thickening agent. It has about twice the thickening power of regular flour. Unlike cornstarch, however, arrowroot is completely flavorless and will not impart a starchy taste into puddings or other dishes that it is used to thicken. Another reason that arrowroot is called for in recipes is that it is extremely digestible, moreso than regular wheat flour.
