Jerusalem artichokes are neither from Jerusalem nor artichokes, but are sunflower-related tubers, with a delicate nutty flavour that is slightly sweet. They are high in iron, potassium and thiamine, and also feed the healthy bacteria (lactobacilli) in the intestinal tract.
Jerusalem artichokes are good for diabetic conditions because they stimulate insulin production and contain inulin (they store their carbohydrates in the form of inulin rather than sugar), and thus can assist in blood sugar control. Additionally, they are low in fat and in kilojoules. To prepare Jerusalem artichokes just wash and scrub them with a brush, peeling is optional.
Jerusalem artichokes are delicious in soups, casseroles, purees, roasts, stir frys or salads. They are very versatile and can be used raw or cooked. To avoid chemical residues purchase certified organic Jerusalem artichokes when possible.
