Sunchokes are thin-skinned, knobby, and resemble the look of ginger. These tubers are the root stem of a variety of sunflower that grows up to ten feet tall. Sunchoke varieties can vary in appearance, some have "eyes" similar to potatoes, some are smooth, whereas others are more knobbed. The tubers have a light-beige to tan colored skin, with a crisp and juicy, ivory flesh. Raw Sunchokes have a texture similar to water chestnuts and a sweet, nutty flavor.
