Jerusalem Artichokes also called Sun Choke, Sun Root, Earth Apple or Topinambour are a member of the Sunflower family & native to Eastern North America. Amazing roasted (in coconut oil or the new Cocova Avocado/Coconut Oil blends), made into soups or raw in salads :)
The skin of the root, which varies in color from light brown and white to purple and red, can be eaten as well, provided that you clean it thoroughly before eating.
Jerusalem artichokes can be eaten raw or cooked, and they make a nice, health boosting addition to soups and salads alike.
