Etymology and preparation
The main ingredients usually include chicken, onions, garlic, green peppers, chili peppers, potatoes, ground cumin, ground Sichuan peppers, cooking oil, soy sauce, and beer.
The chicken is cut into bite size pieces , sauteed with spices and coarsely chopped vegetables, and slow cooked in beer, providing a savory and spicy casserole-like dish. It is usually served with latiaozi or lamian , and shared by family and friends in a communal manner.
Legend has it that this dish was invented by the restaurateurs along the highways, as a quick fix for the often untimely arrivals of the hungry truck drivers. However, its rich flavor and heartiness quickly became a favorite of the region, and even the nation.
