Hot and sour soup is a popular example of Sichuan cuisine. Similar versions are found in Henan province, near Beijing, and in Henan cuisine itself, where it may also be known as hulatang or "pepper hot soup" (胡辣汤). 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.
Soup preparation may use chicken or pork broth, or may be meat-free. Common basic ingredients in the American Chinese version include bamboo shoots, toasted sesame oil, wood ear, cloud ear fungus, day lily buds, vinegar, egg, corn starch, and white pepper. Other ingredients include button mushrooms, shiitake mushrooms, or straw mushrooms and small slices of tofu skin. It is thicker than the Chinese cuisine versions due to the addition of cornstarch.
