TUREEN, a deep dish or bowl, round or oval in shape, and with a cover, made to serve soup at table. The word is a corruption of the more correct " terrine," an earthenware vessel (Med. Lat. terrineus, made of earth, terra). The corruption is due to misspelling in early cookery-books, and an absurd story that the name arose from Marshal Turenne once drinking his soup from his helmet was invented to account for it.
