Traditionally the whole animal goes into one giant cauldron at once — meat, offal, bones, and blood together — and the same pot is often kept simmering and topped up over an entire market day.
Horse or buffalo meat, along with organs, bone, and blood, is simmered for hours in a single large cauldron with a bundle of mountain spices including cardamom, star anise, and dried herbs specific to the highlands, then ladled out hot into bowls shared around the pot. It's a fixture of the weekly market days (chợ phiên) that draw H'mong, Dao, and Tày traders down from surrounding villages in Sapa and Hà Giang.
