Jerusalem artichokes
Other Name
French: topinambour


Helianthus tuberosus

This vegetable is not truly an artichoke but a variety of sunflower
(Compositae), a hairy, tuber-bearing perennial native of North America, where
it was cultivated by the Indians. Contrary to what the name implies, this
vegetable has nothing also to do with Jerusalem. Because of its confusing
moniker, modern-day growers have begun to call Jerusalem artichokes sunchokes
, which is how they're often labeled in the produce section of many markets.

Buying
Select those that are firm and fresh-looking and not soft or wrinkled.

Storage
Keep the tubers wrapped in plastic and refrigerate. They will keep up to two
weeks, but it's always best to eat them as fresh as possible for the best
flavor and nutrition. Their sweetness is known to increase when refrigerated
for a day or two after harvesting.

Nutrients per 1/2 cup serving
327 mg. potassium, 57 calories, 1.5 gr. protein, 1.2 gr. fiber, 10.5 mg.
calcium, 10 mcg. folacin and smaller amounts of niacin and thiamine.

Culinary tips
Scrub sunchokes clean with a vegetable brush. Since much of their nutrients
are stored just under the skin, it's best not to peel them. Once cut,
sunchokes discolor quickly, so it's best to cut them close to serving time,
or cut and immerse them in water with lemon or vinegar to prevent oxidation.

Jerusalem artichokes can be eaten raw in salads or cooked by boiling or
steaming and served as a side dish.

The Jerusalem artichoke has an almost sweet taste, not unlike an artichoke.
Boiled, it can be puréed and turned into a velvety soup.
