Also known as Topinambour, Jerusalem Potatoes, and Canadian Artichokes, the Jerusalem artichoke is a tuber member of the sunflower family. The artichoke was first introduced by the French explorers in Canada to Europe, where it is now extensively cultivated, and eaten in the autumn and winter months.
The artichoke has an irregular, oval shape with short, nobbly protrusions, and is whitish-yellow, sometimes tinged with pink. As it contains insulin, the vegetable has a sweet flavour.
There are two basic ways of cooking artichokes. The first is to boil them. Peel the artichokes quickly and immediately immerse them in cold water, as they dis-colour once peeled. Drop the artichokes in boiling salted water, to which a little lemon juice has been added, and simmer for 30 minutes, or until they are tender when pierced with a knife. Drain and serve with a sauce such as bechamel, or as a vegetable accompaniment to meat or fish.
The second method of cooking arti-chokes is to steam them. Scrub the vegetables thoroughly under cold running water to remove all the dirt. Either place them in a very little boiling water, or in the top part of a double boiler, and steam for 30 to 40 minutes, or until they are tender. Rub off the skins and serve topped with butter.
