小白菜
Tianjin preserved vegetable (; also called tung tsai (), Tientsin preserved vegetable or Tianjin preserved cabbage) is a type of pickled Chinese cabbage originating in Tianjin, China. It consists of finely chopped Tianjin cabbage (箭杆菜; a variety of Chinese cabbage with an elongated shape) and salt. Garlic is also generally added in the pickling process, although it is omitted in versions prepared for consumption by members of certain Chinese Buddhist sects, who practice strict Buddhist vegetarianism and do not consume garlic or other spicy foods. This pickled vegetable is used to flavor soups, stir fries or stewed dishes.
