What is "Jerusalem artichoke"?

Jerusalem artichoke, also known as sunchoke, is a unique root vegetable characterized by its knobby, irregular shape and pale brown skin. It has a crisp texture and a slightly sweet, nutty flavor. Despite its name, it is not related to the traditional artichoke but is actually a member of the sunflower family. The flesh of Jerusalem artichoke is creamy white and provides a delightful crunch when eaten raw or a soft texture when cooked.
