This signature sauce is further enhanced with white sugar, salt, chili oil, and sesame oil, creating a unique flavor profile. The broth itself is intentionally simple, typically consisting of scallion segments and ginger slices to enhance the natural freshness of the ingredients without overpowering them .During preparation, the sesame paste is first diluted with water to achieve an optimal, smooth consistency. Then, the crushed fermented bean curd and leek flower paste are blended in, followed by the seasoning with salt and other ingredients .For the dining experience, a copper hot pot is used for cooking, which ensures excellent heat conduction. The meal is traditionally enjoyed by swishing thin slices of lamb, along with ingredients like Chinese cabbage and frozen tofu, in the simmering broth. The cooked items are then dipped into the specially prepared sauce before eating, embodying the distinctive culinary characteristics of Old Beijing .
