Pao cai (Chinese: 泡菜; pinyin: pàocài; Wade–Giles: p'ao4 ts'ai4; lit. 'soaked vegetables'), also romanized as Pao tsai, is a generic term for pickled, specifically fermented in brine, vegetables in Chinese.[1][2]
There are more than 11 varieties of pickled vegetables across China,[3][4] but pao cai by itself usually refers to Sichuanese pao cai (Chinese: 四川泡菜), primarily produced and consumed in southwestern China.[5] A wide variety of vegetables (including Chinese cabbage, cabbage, radish, mustard stems, long beans, peppers, daikon, carrots, and ginger), are placed with spices into a seasoned brine and kept shut.[6] It is widely used as side dishes, appetizers, and condiments because of its crisp texture, special fragrance, and health benefits originating from its lactic acid fermentation.[7][8] Sichuan pao cai is produced both domestically in locals' daily life and commercially in industry, and it is popular throughout China.
Other names applied to pao cai include Sichuan pickle,[5]Chinese sauerkraut,[9]pickled cabbage.[10]
