Also known as Jerusalem artichokes, sunchokes are not related to the city or artichokes. These tuberous roots look like ginger but are from a sunflower species. Their crunchy texture is similar to water chestnuts and their earthy character is a cross between a potato and an artichoke--a little sweet, a little tart, and very filling. Decide for yourself by eating them raw or roasted, with or without the skin. Try them puréed as soup, chopped up in a quiche, or pickled for a long lasting snack.
