Cardoon is a large perennial thistle in the Asteraceae family, cultivated for its thick, celery-like leaf stalks and immature flower buds, with a flavor reminiscent of artichoke hearts accented by mild bitterness.
History & Origins
Wild cardoon grows throughout the Mediterranean, where it was first harvested and eventually domesticated in antiquity; Greeks and Romans ate it, and by the Middle Ages it had become a mainstay of Iberian, Italian, and French cookery. Selection for large fleshy stalks in southern Europe paralleled the development of the closely related globe artichoke, which most botanists regard as a cultivar of the same species. Spanish settlers later carried the plant to the Americas, where Argentine and Chilean cardoon traditions endure today.
