Hot and sour soup
sour soup of Chinese cuisine
Hot and sour soup is a popular example of Chinese cuisine. Although it is said to be originated in Sichuan, this is actually a variant of hulatang or "pepper hot soup" (胡辣汤) with added vinegar to enhance the sourness. This variation is found in Henan province, and in Henan cuisine itself. Also popular in Southeast Asia, India, Pakistan and the United States, it is a flexible soup which allows ingredients to be substituted or added depending on availability. For example, the American-Chinese version can be thicker as it commonly includes corn starch, whilst in Japan, sake is often added.
