Many Sichuan friends may be unhappy when they see this title. In fact, this mala Tang is indeed from Sichuan, and the name copyright should belong to its hometown. It's just that when I arrived in Lanzhou ten years ago, I did as the Romans do and developed into another appearance. It is said that Sichuan Mala Tang (also called Chuanchuanxiang in some places) needs many guys, such as a small table with a hole in the middle for the soup pot, etc., while Lanzhou Mala Tang can be very hot as long as it has a bigger aluminum pot. The hot materials are even more different. The most distinctive features of Lanzhou Mala Tang are wide noodles and potatoes. Wide noodles are strips as wide as belts made of local starch in Lanzhou, and potatoes are also local specialties in Gansu. Other crops are difficult to grow on the Loess Plateau because of lack of water, but potatoes are of good quality.
