A sunchoke, also known as a Jerusalem artichoke, is a tuber from a species of sunflower native to North America. Despite its name, it is not related to artichokes or Jerusalem. Sunchokes have a knobby, irregular shape similar to ginger root, with a thin, brown or reddish skin. The flesh inside is white and crisp, with a mildly sweet and nutty flavor, often compared to a cross between potatoes and water chestnuts. Sunchokes can be eaten raw, roasted, sautéed, or pureed.
