Canned and Frozen Artichokes
Artichoke hearts, the tender inner part of the vegetable, are available frozen and canned. Artichoke hearts are also packed in vinegar and sauces, to be used like pickles or hors d’oeuvres. Canned whole artichokes are also available, and they may be served like the fresh vegetable. The repeated hand-picking necessary to harvest artichokes makes it a relatively expensive vegetable.
