Top scholar Jun Hong and his concubine Sai Jinhua often come to taste it. Although the current champion hoof is very different from the past in practice, it tastes better. All the raw materials for making the champion's hoof in Jinbang Zhuangyuan Square are made of the hoof rafters produced by Shanghai Food Company, and the specifications are generally 1- 1.25 kg. Boil hooves in water first, remove hair, add 18 Chinese herbal medicines to boil, and then simmer with slow fire. A large iron pot can cook 80 hooves at a time, which takes about four hours. You must use a wok when cooking hooves, because the wok can absorb the moisture generated in the process of cooking, and it can also evaporate the fat in hooves, which is famous for not adding preservatives.
