Mao Du Hot Pot

Mao Du Hot Pot is a specialized variant of Chongqing hot pot where the star ingredient is tripe — specifically, the lining of the cow's fourth stomach, known as 'mao du'. The tripe is pre-treated to achieve a perfect balance of tenderness and crunch, then sliced into bite-sized pieces. The key to enjoying Mao Du is the cooking time: exactly 8 seconds (nine if you like it less tender), known locally as the 'eight-second rule'. Overcook it and it becomes rubbery; undercook it and it's tough. The tripe absorbs the spicy broth beautifully, carrying the full flavor of the beef tallow base. A proper Mao Du Hot Pot spread includes at least 15-20 ingredients, but the tripe is always the centerpiece. The dish is served with a simple dipping sauce of sesame oil, crushed garlic, and vinegar — nothing more, to let the tripe's texture shine.

📖 History

Mao Du Hot Pot dates back to the origins of Chongqing hot pot itself in the early 1900s. When the boat trackers first created hot pot, they used beef offcuts like tripe because they were the cheapest cuts available. The tripe's unique texture — crunchy yet tender — proved to be the perfect hot pot ingredient. As hot pot evolved from a worker's meal to a culinary institution, 'Mao Du' remained the most prized ingredient. Today, a restaurant's reputation in Chongqing is often judged by the quality of their Mao Du.
