Hooves, commonly known as elbows, are the lower parts of thighs and calves, next to claws. Pork is one of the important animal foods on people's table at present. Because pork fiber is soft, connective tissue is less, and muscle tissue contains more intermuscular fat, so the meat tastes delicious after cooking. Pig elbow is divided into front elbow and back elbow, with thick skin, many tendons and heavy colloid. Suitable for cold salad, roast, soup, stew, marinate and stew.
