Knobby tubers have a crisp texture, much like that of water chestnuts. Native to eastern North America, Jerusalem artichokes, also called sunchokes, are perennial vegetables. Their tubers can be eaten raw or boiled, mashed, baked or fried. Smaller and sweeter than potatoes, Jerusalem artichokes have a nutty flavor—and they're low in calories, with just 7 calories per 100-gram serving! The tubers can be harvested from fall to spring and store for 2 months.
