1. Scrape and wash the elbow, boil it in water until it is raw, then pull it out, pick off the bones, and graze a cross-shaped flower knife on the inside (cutting can also be done). It is a good idea to cut the scallions into pieces and the ginger into slices. Wash the greens and set aside. The first thing you need to do is to get rid of all the mushrooms, and then you need to get rid of them.

2. In a pot, add fresh broth (the soup in which the elbows were cooked), scallions, ginger, peppercorns and seasonings, put the elbows skin-side down, and then simmer until the elbows are close to being crispy, then turn them over so that they are skin-side up
