Donglaishun instant-boiled mutton is selected from sheep castrated for one to one and a half years in Xilin Gol League, Inner Mongolia. Because the local water is sweet and the grass is tender, and the grass is rich in minerals, the mutton is tender and tasteless. The selected parts are "upper brain", "cucumber strips", "grinding crotch", "big three forks" and "small three forks" of a sheep, and the yield only accounts for 40% of a sheep's clean meat. In addition, all the sheep used are slaughtered by imams, and the company's preparation center picks the sheep and selects the meat, which is assembled and frozen once.
