The sunchoke is native to Eastern Canada and North America. They were cultivated by the Native Americans well before the arrival of European Settlers. The French explorer Samuel de Champlain grew the plants in Cape Cod in 1605 and brought back to France. The sunchoke became a popular crop in Europe. The Jerusalem artichoke is quite popular in France and was named the “best soup vegetable” in 2002 at the Nice Festival for the Heritage of French Cuisine. There have been several attempts as of late to cultivate an interest in the sunchoke with some success. Interestingly enough sunchokes are now being studied as an alternate food and fuel source.

Did you know Native Americans planted sunchokes on the trails as a precautionary measure to ensure they had a readily available food source as they traveled? It is also nicknamed the “fartchoke” as it is known to cause serious indigestion if consumed in great quantity. For more fun facts go here.
Handle your sunchokes with care as they bruise easily. You can store your sunchokes, unwashed and in a paper bag or wrapped in a paper towel in the crisper drawer of your refrigerator or in a paper bag in a cool, dark space. They should keep for up to two weeks or longer. It is not recommend to can or freeze sunchokes as they discolor.
The sunchoke has roughly the same calories as a potato with little fat and zero cholesterol. It has a very high quality phyto-nutrient profile which includes dietary fiber, antioxidants, minerals and vitamins. Sunchokes are high in Folates, Niacin, Pantothenic Acid, Riboflavin, Thiamin and Vitamins A, C, E, and K. Minerals include Calcium, Copper, Iron, Magnesium and Manganese. Sunchokes are an ideal sweeter for diabetics. They contain Inulin, a zero calorie saccharine and inert carbohydrate that does not metabolize in the human body. High fiber reduces constipation problems and protects against colon cancer. The anti-oxidants provide protection from cancer, inflammation, and viral cough and cold. The sunchoke is heart healthy as it is high in electrolytes, especially Potassium, Iron and Copper which reduce blood pressure and heart rate.
The sunchoke texture is crisp and the flavor is sweet and nutty. They may be eaten raw or cooked. Before eating or cooking, scrub the tubers thoroughly with a vegetable brush. Peeling a sunchoke can be a challenge due to the protuberances and is not necessary as the peels are perfectly edible. However, if you must peel them, slice off the smaller bumpy areas and remove skin with a vegetable peeler. If you will be eating them cooked, you will find it easier to boil, steam or microwave them whole and unpeeled first, and then peel if necessary.
Sunchokes oxidize when exposed to air, just like apples or potatoes. To prevent this, toss with lemon juice before cooking. Here are more helpful hints. One of our favorites is a tip about preventing sunchokes from turning gray when pureed or made into soup (their high iron content causes this to happen): add a pinch of cream of tartar or an acidic liquid (like lemon juice) to the sunchoke cooking water.
Sunchokes are delicious raw and as an addition to a salad and are crunchy enough to make into a slaw. They can also be substituted for water chestnuts and jicama. Sunchokes may also be steamed or boiled whole for 15-20 minutes, or sliced and boiled with a squeeze of lemon juice for 5-10 minutes. Puréed sunchokes are great in risottos and soups. Sliced very thin, drizzled with oil and roasted in a hot oven they make great crisps, and cut into chunks are right at home roasting alongside potatoes. The French are specifically known for their creamy sunchoke soups.
