The production method of soybean oil is actually relatively simple. Those who have made tofu should know that every time the tofu coagulates, the layer of oily skin that appears is the prototype of soybean oil.

And it has not been fermented, and fermentation will denature the oil in the soybeans and make it easier to seep out.

The first step in making soybean oil is to boil the beans, you don't need to boil them for too long, just boil the water.

Then it's time to steam the beans, put the boiled soybeans in the steamer basket and steam them for about half an hour. The beans are almost ripe.

The next key step is fermentation, spread the steamed soybeans on the bamboo basket, and put the bamboo basket into a hot and humid environment for fermentation, waiting for a day or two for it to fully ferment.

After fermentation, the soybeans should be washed with enzymes, and the enzyme bacteria should be washed with water, otherwise the soybeans will continue to ferment, but something will happen.

After doing this, the oil in the soybeans has been completely denatured, and it can be extracted.

The extraction process is soaking. Put the washed soybeans in hot water, soak them seven or eight times, and then leave the soaked water behind. At this time, all the fat in the soybeans has melted into the water. The color of the water has turned milky white.

After completing the above five steps, the next step is to boil the oil. Put the soaked water on top into a pot and bring it to a boil over high heat, then slowly over low heat until the soaked water is thick. This makes soybean oil.

And most importantly, the beans can continue to be used. Not only can livestock be fed, but even people can eat it.

The piece that Li Er saw was written about Qin Ze's method of making oil.

The chapter was written by Song Fang, and after Qin Ze said the method, he immediately presented it to Li Er. Unlike Qin Ze, he didn't realize the value of soybean oil, although it was only a long history, but he was in charge of military food and military equipment for so many years. He had already cultivated a pair of fiery eyes and essence gold.

The emergence of soybean oil is absolutely subversive, and the soldiers of the army have always been vegetarians, and their bodies are already weak. If you have a lot of soybean oil, you can definitely enhance a lot of combat power.

Moreover, people can also use soybean oil for lighting, instead of using mutton fat and lard, which are very flavorful and expensive.

Unlike Qin Ze, who only focuses on a small aspect in front of them, Li Er and they can see further, from a soybean oil, they can see the future.

"The pedal spinning wheel, locust military rations and this soybean oil are made, this is not bad, but how can it be so unmotivated." Li Er looked at the concerto, on the one hand, he was happy that he had such a talent, but on the other hand, he was worried about Qin Ze's non-compliance.

Qin Ze gave him the feeling that he was like a lazy horse, as long as there was grass in front of him, he would never move a step.

If you want to get him moving, either give him a whip or pull the grass off in front of him. Otherwise, no matter how much hay you put in front of him, he won't move a step.

"Ugh." There was a long sigh, but the eldest grandson on the side who listened let out a chuckle.

Li Er turned his head to look at his wife, who was looking at himself eating and laughing, and he also laughed.

"Second brother, is it still for that kid?" Now even if he is the eldest grandson, he directly calls Qin Ze a kid. From the heart, it's not a kind of love.

Since the day her husband became the emperor, he has rarely been able to sigh like this. This kind of joy and sorrow is mixed, but it is full of human warmth.

Li Er pursed his lips and said angrily: "As the king of a country, I have to follow that kid to pick up the leaks." Last time the pedal spinning wheel, this time the soybean oil. obviously has such intelligence, but he doesn't want to serve Datang. If it hadn't been handed in by someone else, I wouldn't have known such a good thing. ”

Li Er, the emperor, was also a little helpless when he met Qin Ze, and the other scholars all sharpened their heads, and they were bent on pleasing themselves.

But Qin Ze is good, he doesn't have the slightest plan, he wants to get his method, and he has to follow him to pick it up.

If you call him and whip him, I'm afraid it will chill this boy's heart. Just like him, if he is ruthless. It is estimated that they can escape directly from Chang'an.

But if you don't fight, this kid is holding a belly of ink, and he wants to be happy every day.

"Hiss~"

Li Er grabbed his head and took a long breath.

It was the first time he had been an emperor for so long that he was upset by this kind of thing.

The eldest grandson on the side also smiled even more happily, his pretty face flushed, and he looked at Li Er with fascination.

also discovered the strangeness of his husband, and the eldest grandson glared at Li Er angrily, touched his stomach, and looked proud.

She is indeed qualified to be proud, she gave birth to two sons for Li Er, who else in the harem is as powerful as her?

Li Er looked at the eldest grandson's little daughter's invitation expression, and also followed hehe. But he suddenly remembered something, and said to the eldest grandson: "Cheng Zhijie also said that the kid made some food today, and it tasted pretty good." Do you want to taste Guanyin? ”

Qin Ze annoyed Li Er, and Li Er tortured Qin Ze, this is Li Er's train of thought.

The eldest grandson didn't know Li Er's thoughts, so he naturally nodded in agreement.

So Qin Ze, who was waiting to get off work with Cheng Laodemon in the military courtyard, waited for such a holy metaphor.

It was Ruan Quan, the chief eunuch, who came to preach the parable, and the content of the parable killed Qin Ze unexpectedly.

"Come to the imperial dining room and make a few steamed buns."

This is the content of the parable, and no matter how you listen to it, there is an incredible feeling.

The Tang Dynasty Son of Heaven who is the Emperor of the Tang Dynasty in one word, the holy parables that came out turned out to be like this, how can you make Qin Ze believe it.

It's just that looking at the seriousness of the eunuch Ruan Quan's face, Qin Ze can only follow him well.

"The legendary parable turned out to be like this. The dignified king of a country actually deliberately passed out a holy metaphor for a cage of steamed buns...... "Qin Ze suddenly felt helpless in his heart, if this holy metaphor let Du Ruhui and Fang Xuanling, the doctor of the ceremony, know that eighty percent of them will fight to the death with Li Er.

But who made the family a monarch, the foundation of the Tang Dynasty was laid down by others.

Ruan Quan is a very strict person, and he definitely doesn't say what he shouldn't say, which is why he can stay by Li Er's side.

This is a tall little old man, estimated to be forty or fifty years old. He looks old, but he is not slow to walk at all, and his vigorous and resolute methods almost make Qin Ze unable to keep up.

It seems that this guy doesn't shake his shoulders and crotch, and the whole person is like floating on the ground. I didn't make a sound when I walked, and I couldn't hear the sound of breathing. If it weren't for the fact that he could see the shadow on the ground, Qin Ze would have been a little skeptical that this guy was a ghost.

In this way, Qin Ze was taken to the imperial dining room, and Qin Ze, who thought that there was such a luxury here, couldn't help but be a little disappointed after seeing everything in the kitchen clearly.

In recent years, natural disasters have occurred frequently, and I heard that several rats in the treasury have starved to death. In order to reduce expenses, Li Er also tried to keep things simple.

Not only the aspect of food is simple, but also the aspect of clothing. I heard that Li Er wanted to repair the Lizheng Palace, but he was so poor that he had no money.

When the emperor was in this position, Qin Ze didn't know what he was trying to do.

The Imperial Dining Room is not only responsible for Li Er's meals every day, but also for the meals of the ministers of the Imperial Palace.

The so-called pilgrimage day, that is, the day when you want to enter the palace to see the emperor, the Tang Dynasty stipulates that officials below the third grade go to the court every Monday or five days every month, and do not need to come every day. And those with three grades and above have to come to court every day.

And after each court meeting, Li Er would let the officials of the previous court sit on the ground and eat a meal under the eaves of the palace and on the corridor, which is called "eating under the corridor".

What is there to eat in the "Corridor Food"? It is estimated that at most there will be four dishes and one soup, and it will not be so simple and cold that it will lose the face of the emperor, but don't expect the delicacies of the mountains and the sea. The meat ration of the abnormal staff is three sheep a day, and the mutton distributed to everyone's mouth should not be too much

As for the prime minister, it would be better, you can go to the "political affairs hall" to eat. And the so-called prime minister of the Tang Dynasty was actually an official of the three products under the Tongzhong Shumen. Only these people can eat the most delicate and high-grade small stove rice.

But no matter how delicate it is, it is nothing more than boiling, steaming, and baking. It's not complicated either.

But after all, it's an imperial dining room, and there's still a lot of stuff in it. Although I didn't see abalone and sea cucumber, I still had all kinds of spices, chicken, duck and fish.

Anyway, just let yourself make a basket of steamed buns, and you don't need many ingredients.

It's just that Qin Ze was disappointed that he didn't find a piece of beef even in the imperial dining room. It seems that even Li Er doesn't often eat beef, generally speaking, there is only one possibility that ordinary people can eat beef, that is, their cattle are sick and dead, or injured and cannot be farmed, so they can be allowed to be slaughtered.

And before that, you have to report to Jingzhao Mansion, and you can only slaughter it when the government agrees.

For Li Er, although there is no need to report a beef, there is still a large group of counselors staring at it.

Without beef, Qin Ze's idea of trying beef buns was shattered.

When the eunuch Ruan Quan brought Qin Ze to the imperial dining room, because it was not time to eat, most of the cooks were dealing with the ingredients. In the entire imperial dining room, only three or four cooks remained.

Ruan Quan gave an explanation to the imperial chefs, saying that His Majesty wanted to eat steamed buns, and asked them to assist Qin Ze in making a few cages.

Although those imperial chefs were a little unconvinced and wanted to listen to Qin Ze's words, as soon as they heard that it was His Majesty's meaning, they became honest one by one.

Not to mention anything else, if you can ask Your Majesty to personally name and eat, it will definitely not be bad. If you learn it yourself, won't it be very easy to please Your Majesty in the future?

With this idea in mind, the four imperial chefs worked even harder to help Qin Zelai.

And Qin Ze had a completely laissez-faire attitude towards this, so much so that the four imperial chefs couldn't help but laugh at Qin Ze in their hearts, saying that he had a problem with his brain. I don't even know how to cherish such a delicacy, so I give it to others casually.

The Tang Dynasty was still too poor, the society had just begun to develop, and there were too many things to accumulate.

Qin Ze naturally won't sweep himself away, he will take it if he wants, anyway, it is inherited from you, and it will be returned to you.
