Tianjin preserved vegetable (Chinese: 天津冬菜; pinyin: Tiānjīn dōngcài; literally "Tianjin winter vegetable"; also called 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 vegetarianism and do not consume garlic or other spicy foods. This pickled vegetable is used to flavor stir fried or stewed dishes.
Tianjin preserved vegetable is commercially available in earthenware crocks or clear plastic packages.
Finely chopped salted vegetables usually come in an earthen pot. It is often used in soups, porridge and dry noodle dishes for added flavour. Needs to be rinsed to get rid of sand. The vegetables age naturally to a dark brown color. Test out a piece to determine its saltiness before use. It can be found in a Asian Market.
