Live broadcast: Ancient people accompany me to make up lessons

[Sitting at the dining table outside and sipping coffee, Xiaoxiao quickly started calling the lucky spectator No. 2. 】

Xu You, a young vendor from the Western Han Dynasty, looked at the wilted fruits in his load, and then remembered the juicy vegetables that the anchor grandma brought yesterday, and said with envy: "Is there any way to prevent fruits and vegetables from spoiling?"

How to preserve food?

Upon hearing this question, farmers and businessmen basically stopped working and began to listen seriously.

["Fruits and vegetables are not bad. There are many ways to do this." When asked about another one that he had learned in school, Xiaoxiao secretly breathed a sigh of relief.

"The most basic thing is to keep it fresh, freeze it or refrigerate it."

She took two steps to her refrigerator and opened the refrigerator on the right. The white light came on, and a dazzling array of fruits and vegetables as well as bottles and jars were neatly stacked inside.

"For example, in this home refrigerator, this area is the refrigeration area, and the temperature is generally between 5 and 8 degrees Celsius, and it is written on it. The one on the left is the freezer area, which is generally -18 degrees Celsius."

The cabinet door on the left was also opened, and cool white air instantly came out of it. Different meats and colorfully packaged fast food were placed inside.

When the refrigerator was closed, there was a beeping sound, and the time and temperature numbers on the cabinet door lit up before going out. 】

Li Chengqian stared at it with wide eyes, poked his brother's arm, and whispered: "Qingque, did you see that there is time and temperature on it, it's so magical!"

Li Tai wiped his saliva, his eyes lingering on the closed refrigerator door.

"Brother, watermelon!"

In the refrigerated area on the right, there is a big, round, red, and extremely beautiful half watermelon, watermelon!

Have you ever remembered that you owed me a watermelon yesterday?

Li Chengqian:......

Just say hello to Xigua, don't talk nonsense.

Li Tai didn't care, his mind was already attracted by the magical cabinet in the anchor's house.

On the left are big watermelons, big tomatoes, boxes of unknown things, and bottles of colorful water that looks like wine. On the right side there are dumplings, wontons, glutinous rice balls with beautiful colorful pictures, as well as the beef patties and xiaolongbao that the anchor ate!

It turns out that it is black pepper golden beef patty, and the name is very delicious as soon as I hear it. Li Tai pressed his tongue against the roof of his mouth and swallowed.

There are many people like him, but Liu Che was also attracted by the photo deception and was very curious about the taste of the food. There are also those colorful jars and crystal bottles on the right, they must be wine!

What do those wines taste like...

Those who were listening carefully to the lecture all started thinking, it is true that food does not go bad easily when it is cold, but what should they do if it is hot and they do not have this magical cabinet?

[Xiaoxiao opened another cabinet under the refrigerator, squatted down and pointed at the bag containing flour and rice, which was tightly clamped by the clips: "If you store the food at room temperature, you must put it in a dark and cool place. Keep it cool. Dry, absolutely no light and no moisture.”

She closed the door, thinking of their backward technological level, and added: "If it's too hot at home, you can dig a cellar. The temperature underground will be much lower. But be careful about moisture, bugs, and mice."]

People who have no experience in digging cellars suddenly light up: "That's right! If the ground is hot, you can go underground! Mom, I'll dig a cellar at night too!"

His mother hit him: "Didn't you listen to what the anchor said? It needs to be dry and there must be no rats or bugs. Go back and discuss it with your father and dig a small one to try."

Xu You sighed. The cellar was suitable for storing food for a long time, but it was not suitable for small traders like him who sent it to the city to sell it.

He clasped his palms together and prayed to the sky: "Please host, give me some more storage skills!"

[Xiao Xiao rummaged through the kitchen, picked up a bottle of pickles and a can of plums, and introduced: "There is also a pickling preservation method, which generally uses salt or sugar to preserve food. This bottle of pickles is to dry out the moisture first, and then add Salt and pepper seal it.

Let me take a look... The shelf life is one year, but this is only the best before date, and it does not mean it is bad after the time is up. "

Putting down the jar, she continued to introduce: "These plums can be pickled with salt or sugar, or they can be directly dried and made into dried fruits. In addition to plums, there are also grapes, plums, and peaches, which can all be made into dried fruits. There are also Persimmon.

Not only dried fruits, but also salted fish and bacon are all salted, and all kinds of dried shrimps and scallops, kelp and seaweed can be dried..."

Opening the cabinet, Xiao Xiao pulled out some dried kelp, seaweed, shrimp and the like to show them, and the system lens zoomed in one by one. 】

As long as the family is rich, they have seen these things in their families, especially the bacon metaphors and dried fruits. They have also eaten them. They are just curious about those jars that are transparent and not like crystal, and those shiny ones. That bag that creaks when you pick it up is something.

The large persimmon cake that was complete and covered with icing made many people salivate when they saw it. There was also the pickle jar. That color and sound, was it crystal or glass? Such beautiful jars of pickles…

Too extravagant and wasteful!

[Xiao Xiao opened the refrigerator again and took out a can of canned yellow peaches and assorted jams.

"It can also be made into cans and jams. For example, this canned yellow peach can be boiled with rock sugar and packed. You can make it at home and store it for more than ten days. Or you can cut them into pieces and cook them slowly to boil out the fructose. You can add some sugar to make jam according to your taste, and it will not go bad easily in a high-sugar environment.”

She put everything back and added: "There are many vitamins in fruits and vegetables, which are nutrients needed by the human body. Canning them makes it easier for the body to replenish nutrients when there are no fresh fruits and vegetables. Sometimes when you are sick, You can eat some canned fruit to add sugar to your body."]

Yes, these cans and jams are also made from fruits. They can cook them with less salt, and they can cook them slowly if they are not too sweet. They can always cook out some sugar.

During the Song, Ming, and Qing dynasties when the sugar industry was developed, businessmen in sugar-producing areas suddenly saw that making jam and canning was a good way.

Although they can't put a small jar upside down like the anchor does without leakage, they can make a large jar or even a large tank at one time and sell it by the kilogram.

The children were drooling, and the adults were thinking about whether they could try it. But the doctors noticed the vitamins and nutrients mentioned by the anchor, and the sugar. Is it the same thing as white sugar?

There were pictures of food on the colorful packaging bags, and Li Tai began to fantasize about when he would be able to contact the anchor and want to buy food from her...

The questioner Xu You was overjoyed, put down his burden and kowtowed to the sky.

He also has peach and plum trees at home. There is no sugar in canning, but you can still try dried fruits and jams.

Several dynasties held court meetings, and the kings also heard about it. However, except for the large amount of salt and sugar required to make canned vegetables and pickles, some people were considering whether to directly run the government. They knew that they could not control the people in other ways. .

Some people also made a rough calculation and found that vegetables will shrink after being pickled, and the same will be true for those made into jam. Even so, it is better than picking things, leaving them uneaten and unable to be sold.

Zhu Yuanzhang looked at the dry goods such as shrimps, scallops, kelp, and seaweed, and felt a little confused.

In this future generation, the grain production is so high, the problem of eating is solved, and there are all kinds of fruits and vegetables, why do we still need to buy these seafood? Looking at the map, she is not a coastal person...

Even if he didn't know what class was, he was still eager to know the origins of the descendants of Marquis Wu he believed to be, why there were so many good things at home, those books, and the lessons she wanted to learn...

Those poems that I had admired appeared before my eyes again, such as "Millions of Heroes", "Workers and Peasants", "Romantic Figures"...

Zhu Yuanzhang tightened his grip on the pen, and for a moment he didn't know whether this sky curtain was an opportunity for the Ming Dynasty.

Compared to him, Kangxi was already in dire straits.

Those anti-poems, anchor Zhuge's Han identity, the high-hanging canopy, the deposed prince...each one made him anxious.

Now we can only quickly cultivate high-yield crops, stabilize the situation, and appease the restless south.

Yinreng, who was already barefoot and no longer afraid of wearing shoes, was much more relaxed than his father and brothers. He went directly to the palace to ask for rock sugar and some fresh fruits. He wanted to cook canned fruits.
