Specific methods:
1, prepare food in advance
Two pork bones, 500g tofu, 0/5g medulla tetrapanacis/kloc-,a little yellow wine and a little edible salt. If you are afraid that the soup is too greasy, you can also prepare appropriate vegetables in advance to get rid of it.
2. Practice
Wash the bones with cold water first, then put the pig bones into a pot and add a certain amount of cold water, then cook the pig bones with cold water to remove the foam from the soup.
Fish out the pig bones and wash them in cold water later. Then put the pork bones in a pressure cooker, add appropriate amount of cold water as needed, then add medulla tetrapanacis and rice wine and stew for 30 minutes. You can also cook in a stone pot, but it takes a long time to cook in a stone pot, and it takes at least one and a half hours to stew.
After the bones are stewed, put the vegetables and tofu into the pot and stew for another ten minutes on medium heat. After vegetables and tofu are cooked, add a little edible salt to boil.
Pregnant women should swallow the meat together with the bones when drinking prolactin bone soup, and then eat some vegetables and tofu appropriately. A variety of food combinations are more conducive to lactation.
