Li Yu pointed to Tang and said, "Sage, mother, this soup is also something that the child has only figured out recently. The people in southern China are weaker than those in northern China, so they suffer more losses when fighting against the Northern Dynasties, but the Northern Dynasties suffered even more losses when facing the Khitan barbarians. After thinking about it, the child turned over the classics and felt that the root of the food was the meal. The Khitans were very poor, especially the habit of knocking and sucking marrow. From princes and nobles to ordinary people, the bone marrow is the essence of bones. Therefore, they are strong and can wear heavy armor and hard bows."

"But this food is fishy and the southerners eat a light diet, which is really difficult to eat. Therefore, the child thought of a solution. Please see this soup. He chopped the big bones and simmered them over low heat. In order to understand the greasyness, he specially added a good rice vinegar to season them, and then filtered off the broken bones."

In fact, people say that bone soup can supplement calcium, but the calcium content in bone soup is minimal because calcium is insoluble in water.

Therefore, it is necessary to add vinegar to form calcium acetate before it can be absorbed and utilized by the human body.

But this set of rhetoric has no effect on the ancients... Li Yu can only find other excuses.

"But Yu'er, this bone marrow is greasy, but when I see the soup is milky white, there is no oil on the face. How did you do this?"

"This is simple. Fujiwara Yahei said that their island countries have always had the habit of eating kelp, and after this product is processed, the taste is not bad. This product has a wonderful use. After absorbing the oil in the soup, the taste will become more plump and beautiful."

He said this, but he was muttering in his heart, "Nonsense, this milky white soup is the result of the emulsification of oil, but you don't believe this scientific knowledge, so you should follow the traditional routine."

"The fragrance contains meaty fragrance, which is really wonderful. And why is it so fresh? Dagu is never known for its freshness?" Li Jing said very well when he heard him say it, and with the fragrance emitted by the hot soup, he couldn't help but take a sip.

"The kelp itself can improve freshness, but in order to make the soup more palatable, the child also added shrimp skins to it, so the soup was considered a success. Mother, do you try it too?"

Queen Zhong said that her daily diet was mainly light. Seeing that the bone soup was a little frowning, she saw that her son was eager to persuade him to go in, she still scooped half a spoon and dripped his tongue a little. She originally planned to drink it, even if she had finished drinking it, it would not make her son feel excited.

As a result, I drank half a spoonful of soup and scooped up another spoon to savor it carefully.

"This soup is really delicious..."

"Hehehe, the mother praised the child and she didn't want to be so stingy." After saying that, Li Yu wiped his forehead and said to himself, "It's a troublesome to add calcium to it, and he has to make up such a big cliché."

Several younger brothers also followed suit and drank the soup. After taking a sip, they all praised it for its wonderful taste.

Since the emperor and his family said that the soup tasted great, the emperor's imperial kitchen often cooked this soup for everyone in the palace to eat.

This soup is not only delicious, but the key is to be easy to cook. Except for the troublesomeness when knocking on the bones, the other aspects are similar to stewing randomly. As long as the fire in the furnace is burning, the soup will be similar to stewing for one hour and stewing for two hours.

It soon spread to the people. The people never get meat and fish all day long. When they are really hungry, they buy some meat and bones to make soup, so the mass base is very strong.

But small families are not very particular. They add some salt for a while and then eat it. The main reason is to make the oil and water there, and they can only make the taste.

Some unique practices in Chinese accounting methods are also integrated into it, such as the "Heaven and Earth Joint Gate" must be passed as the checkout action by the end of the year. Due to the scientific setting of the accounting system, the numbers between the general ledger and the sub-accounts can definitely be checked.

Once it cannot fit, it means there is an error. Since the double accounting method is a business and the incoming and outgoing accounts, it is very easy to follow up on each business.
