Specific steps:
1. Prepare your favorite meat and bones. After cleaning, boil water in a pot. After the water boils, add the bones and cook for two or three minutes, then boil the blood. Then take out the bone and rinse it thoroughly.
2. Change another pot of water, bring it to a boil, and remove the fishy smell of two pieces of ginger. Then boil it on medium heat, skim off the floating powder, turn to low heat for 2-3 hours, and then turn to low heat to keep the soup slightly boiling for about half an hour, so that the soup will be more pure.
3. Put the fresh-keeping bags on bowls or plastic boxes respectively.
4. After the soup is completely cool, remove the meat, filter out the meat residue and impurities, and then pour the soup into a fresh-keeping bag wrapped in a bowl. The amount poured into each bag is exactly what you need to cook soup every time. Then fasten the bag with buttons.
Put the bag and bowl together in the refrigerator, so as to ensure that the bag will not be deformed and broken by the soup.
6. When you use it, take out the broth ice and put it directly in the pot to cook and melt. ?
