Chorogi which is also known as Japanese artichoke, Knotroot, Chinese artichoke and Crosnes refers to a hairy plant which is a native of China and Japan. It has small white tubers that have a sweet, nutty taste similar to a jerusalem artichoke. Chorogi is seldom found in the United States but, if available, it should be purchased when firm and white. Chorogi can be refrigerated in a plastic bag up to a week. Chorogi can be eaten raw, or boiled, baked or steamed.
