Dry-steam shark's fin for 20 minutes, then boil it in a pot for 30 minutes, then cool it with cold water (add 2 slices of ginger to remove fishy smell), soak the supercooled shark's fin in clear water, and put it in the refrigerator for one night; 2. Steam the fish glue, take it out, soak it in clear water and put it in the refrigerator overnight).
Step 2: Cook the soup stock (after cooking the soup with pig bones, take out the bones and leave the soup base, add the cut fish glue and wings and continue to cook until the soup is thick, and add 2 or 3 slices of ginger and cooking wine salt when leaving the soup).
Step 3: Stir-fry shredded pork and ingredients for later use (add shredded pork, auricularia auricula and Flammulina velutipes in turn and stir-fry until 7% mature).
Step 4: Pour the fried ingredients into thick soup and boil, and prepare sweet potato starch at the same time.
Step 5: slowly pour the sweet potato starch into the thick soup and stir it with chopsticks or spoon until it becomes thick.
