Orzo is Italian and means “barley”, from which orzo was originally made. However, in common usage in the United States, orzo is understood to mean rice-shaped pasta, slightly smaller than a pine nut. It is frequently used in soups and baked casseroles. Despite its rice shape, orzo is made not of rice but of hard wheat semolina. It is also known as risone in Italian, manéstra or kritharáki in Greek, and şehriye.
