How to make the soup in the noodle restaurant?

Ingredients: ribs, onions, ginger, cooking wine, salt.

1. First, put the pig bones into a pot to boil, remove them and wash them.

2. Step 2: Boil the cooked pork bones, onion knots, ginger slices and water in a pot.

3. Then turn on the small fire and continue to cook. If there is froth, skim it off.

4. Cook for about 2-3 hours until the soup turns white and the pork bones are crisp and rotten.

5. At this time, use the filter again, pour the soup in to filter out impurities such as onions and ginger, and then let it cool.

Finally, put the soup in the refrigerator and use it whenever you want. It is best to make soup with pig bones. The boiled soup is more fragrant, without cavity bone, but it tastes bad. If it is too greasy, you can skim off the solidified oil slick after the soup cools.
