Hulatang

Hulatang, also known as hot pepper soup or spicy soup, is a kind of Chinese traditional soup originated in Henan Province, and became popularized in both Henan and Shaanxi Province. Chinese immigrants have introduced it to the United States, where it is known as "spicy soup". It can be divided into two different versions in Henan: Xiaoyaozhen version and Beiwudu version. As its name—literally the characters 'pepper' + 'capsicum/chilli' + 'soup'—implies, capsicum and black pepper are put into the broth made by beef soup. The exact origin of the soup cannot be accurately pinpointed now, but since the pepper, the main ingredient of the soup was not introduced to China until the Tang Dynasty. The soup was dubbed came into being after that, around Song Dynasty. One theory is that soup with pepper originated from the Huizong period in the late Northern Song Dynasty. Legend has it that Emperor Huizong of the Song Dynasty was addicted to eating, drinking, and playing, which filled the whole country with extravagance.
