Along with basil, oregano, rosemary and parsley, sage is one of the most popular herbs in Italian cooking and is used in every region. It is a perennial plant with evergreen oval leaves that are velvety to the touch. The grey-green leaves contain a fragrant oil that is delicious with white meat like veal, pork and chicken. Among the most popular ways of using sage are with calves’ liver sautéed in butter and in ravioli or tortellini, along with meat and vegetables and Parmesan.
