Sunchoke

Sunchoke, also known as Jerusalem artichoke, is a species of sunflower cultivated for its edible tuber, which has a crisp, nutty flavor reminiscent of artichoke hearts and can be eaten raw or cooked.

History & Origins

Sunchoke was cultivated by Native American tribes, particularly the辽incan and Algonquian peoples, long before European contact. French explorer Samuel de Champlain brought the tuber to Europe in 1605, where it gained popularity in France and England during the 18th century. It was promoted as a food crop by European agriculturalists during World War II as a substitute for potatoes. Today it is widely grown in France, the United States, Canada, and Australia, though it remains a niche vegetable.
