It is necessary to talk about the soup pot here. The soup pot mentioned in Liu Tai's medical book is the kind of pot that can't be opened at 100 degrees, that is, when the power is cut off at 100 degrees, the soup will not overflow. In the past, all the pots had to be modified and a thermostat changed. Now many pots have this function. Some netizens recommended: "One particle casserole", produced by Jianshijia Power Plant in Shunde District, Foshan City. It's a 6-liter pot, which sells around 300 yuan. You can check it online.
After Baoyuan soup is ready, pour it into a big pot and dump all the dregs, because all the nutrients have entered the soup. Some old people are reluctant to throw them away, so they have to dip them in soy sauce. In fact, those residues are not nutritious, even if they are given to cats and dogs, they will not be eaten.
The soup cools naturally, and then put it in the refrigerator for refrigeration. Take it out the next morning, remove the oil slick from the soup, heat it again, add some salt, and then divide it into small golden bowls, one in the morning, one at noon and one at night. This kind of broth is called Baoyuan soup. The color of the soup is light yellow. Drinking Baoyuan decoction for a long time can make the skin smooth as jade.
