Mala is a brothy, spicy sauce consisting of Sichuan peppercorns, chili peppers, oil, and a handful of various spices. In Chinese gastronomy, it is considered as one of the most popular sauces with many regional varieties. The sauce is so spicy that it is even implicated in its name, the term málà literally meaning numbing and spicy, caused by the Sichuan peppercorns.
Although the origins of the sauce are still unclear, the most popular theory suggests that it was invented in Sichuan in the 19th and 20th century, when it was full of pier workers who were regularly eating cheap foods such as beef stomach, kidney, and solidified blood.
