酸菜湯, or "sour cabbage soup," is a traditional Chinese dish known for its tangy flavor. The main ingredient is 酸菜, which is fermented Chinese cabbage, giving the soup its distinctive sour taste. It is often prepared with various meats, such as pork or beef, and flavored with spices and herbs. This soup is popular in many regions of China, especially in the northeast, where 酸菜 is a staple food during the winter months. 酸菜湯 is not only comforting but also nutritious, as it combines the benefits of fermented vegetables with protein-rich ingredients.
