by Europeans it was called Girasole, the Italian word for sunflower. The Jerusalem artichoke is a type of sunflower, in the same genus as the garden sunflower Helianthus annuus. Over time the name Girasole transformed into Jerusalem, and to avoid confusion people have recently started to refer to it as sunchoke or sunroot, which is closer to the original Native American name for the plant.
The artichoke part of the Jerusalem artichoke's name comes from its taste of its edible tuber, which is a cross between a radish and an artichoke.
The tubers are gnarly and uneven, vaguely resembling ginger root, with a crisp texture when raw. Unlike most tubers, but in common with other members of the Asteraceae (including the artichoke), the tubers store the carbohydrate inulin (not to be confused with insulin) instead of starch. For this reason, Jerusalem artichoke tubers are an important source of fructose for industry. The carbohydrates gives the tubers a tendency to break down and dissolve when cooked, in addition to giving them a legendary facility to produce flatulence.
Jerusalem artichokes are sold in the produce departments of many supermarkets. The freshest roots are plumpish and vibrant in appearance. If they are left too long in the open, they become wrinkled and soft and can develop a bitter taste.
