Arrowroot is a white gluten-free powder extracted from the root of a West Indian plant, Marantha arundinacea.
It looks and feels like cornstarch, has no flavor and is used as a thickening agent for sauces, fruit pie fillings, glazes, and puddings. To use arrowroot, mix it with an equal amount of cold water and then whisk it into your hot liquid for about 30 seconds.
