Beans are a really good thing.

It can be used to squeeze soybean oil and make countless delicious flavors.

Soaking in water can be ground into soybean milk, a layer of oil skin on the surface of boiling soy milk can be made into soybean skin, adding a little gypsum can be made into tofu brain, pressing dry a little can get water tofu, and pressing half of the water to get dried tofu.

If you accidentally put it bad or moldy, you can still make stinky tofu and edamame tofu...... Of course, the conditions for the generation of these two alternative cuisines are more harsh, so don't mess around if you don't understand.

Early in the morning of the second day of the Lunar New Year, Zhang Xi, who was full of sleep, got up very early, and after doing a set of stretching exercises in the yard, Zhang Xi came to the kitchen backyard and instructed Xiao Qibao to try to make tofu with nothing to do.

I have already taken Xiao Qibao to do it once, but Xiao Qibao's understanding in this regard is not outstanding, and he has not been able to fully master the process, so Zhang Xi once again pointed out Xiao Qibao.

The first time I made tofu, I just made water tofu, and this time, Zhang Xi plans to make several other tofu products together.

Tofu brain is easy to make, but there is no soy sauce in these years, only soy sauce, dried shrimp and seaweed can only be seen on the beach, anyway, Zhang Xi has never seen it since he crossed over, and as for the meat foam, he is even more reluctant to put it.

So, Zhang Xi will add some water and a little salt to the sauce, boil it and pour it on the tofu brain, and is about to eat it, Kou Feng arrived.

People come to visit, the etiquette should be thoughtful, and it is close to breakfast time, Zhang Xi naturally invited Kou Feng to eat together, and the staple food is the noodles and a bowl of tofu brain left over the day before yesterday.

The tofu brain poured with sauce is really not delicious in Zhang Xi's eyes, and he even feels a little uneatable, but in Kou Feng's eyes, this is simply a heavenly delicacy.

It's not that the food industry was underdeveloped in this era, in fact, some aristocratic and court cuisine was still very good.

But Kou Feng, this kid is not from an aristocratic background, although his uncle and mother are relatives of the Han family, but the meaning of the existence of the Han family relatives in this year is probably equivalent to Zhang Xi and the Jade Emperor having the same surname, which is meaningless.

Therefore, Kou Feng has never eaten much food at all, and now he can eat tender tofu brain, which is still served with salty and fresh sauce...... He ate three bowls of this tofu brain, and he was full of praise.

Seeing Kou Feng eating so happily and frequently making delicious sounds, Zhang Xi suddenly felt a sense of pride.

A sense of superiority and pride that comes from modern society over the turtles of this era.

Prompted by this sense of pride, Zhang Xi, who had a hot brain, had to take Kou Feng to visit his "Tofu Workshop" together, completely ignoring the resentful eyes of Xiao Qibao, who was already in a hurry.

When I arrived in the kitchen, I saw the soy milk in the wooden barrel and the tofu that was still being pressed...... Kou Feng watched and was amazed.

"Sir, you mean that this delicacy is made with bean mushroom?!" Kou Feng looked surprised and asked a little curiously, "What is this big stone pressing?!" ”

Kou Feng saw that the water tofu was still being pressed and removed.

"Go to the New Year's Lord's banquet, hasn't the little general seen it, this is the tofu!" Zhang Xi said a little proudly.

"How can a gentleman make such a delicacy?!" Kou Feng was even more surprised, looking at Zhang Xi's eyes with a little admiration.

This time Zhang Xi was even more proud.

"Prizes, prizes!" Zhang Xi laughed and said prominently, "This thing has been in the Han Dynasty before, and it is not a rare thing..... It is also a coincidence, according to legend, when the former king of Huainan of the Han Dynasty was alchemy, he added a little gypsum to the soybean milk, and he unexpectedly got such a delicacy. ”

At this time, Xiao Qibao was completely desperate, and his master had already leaked all the recipes.

Kou Feng was also surprised.

People in these years, whether they are ordinary people or wealthy families, attach great importance to some family secret recipes, and some people can even sacrifice their lives to protect each other for the family secret recipes.

In Kou Feng's opinion, few people in the world know about this tofu making craft, and it could have been cherished as a family heirloom, but Zhang Xi told Kou Feng directly without care.

This is also the reason why Little Qibao has been in a hurry.

In Xiao Qibao's opinion, the owner of his own house should not bring an outsider into his backyard to peek at his secret recipe.

In Xiao Qibao's eyes, Kou Feng is an outsider.

But in the eyes of Kou Feng, a half-grown child, Zhang Xi, who has only seen three sides, is willing to tell himself all these secret recipes, which is really not to treat himself as an outsider.

People in this era, although there are also those who have ghostly thoughts and deceitful people, but most people's minds are still relatively direct and simple.

It is not uncommon for them to become confidants at first sight, not to mention far away, and the three brothers Liu Guanzhang who are close at hand are the best proof of this.

Kou Feng is now full of emotion, and his favorability towards Zhang Xi is rising, and he feels that Zhang Xi is a ...... Well, he's a good guy.

But Zhang Xi didn't know so much, because he didn't realize that he had leaked the secret recipe.

Tofu, this thing is almost rotten on the street, who hasn't eaten it, and how many people don't know how to make tofu....... In modern society.

So Zhang Xi didn't realize that making tofu in this era actually belonged to the secret recipe category.

Not only did he not realize it, but Zhang Xi also began to talk to Kou Feng endlessly about the benefits of tofu.

Not to mention what tofu skin, dried tofu and other foods to eat, the most important thing is that this thing can squeeze oil and provide vegetable protein.

"Can you make as much oil as you can?!" Kou Feng was surprised again, and after being surprised, he looked solemn and asked, "Sir, do you know the method of oil?!" ”

"This ..... The brook doesn't know! Zhang Xi was slightly embarrassed and said.

Soybean oil squeezing, Zhang Xi won't, really won't.

In modern society, vegetable oil is machine-operated, and it is OK to press a button, and the oil is squeezed by hand..... It's not a professional to do this, who would.

Besides, soybean oil is rarely used in modern society, and the oil yield of soybeans is not high.

But what...... Well, I just said so much, but now when people ask you, they won't ..... It's a bit embarrassing to brag about it.

It's a bit of a loss of face.

Quickly remedied it a little, and said, "Although the stream doesn't know the details, it ..... Most of the time it's ...... extracted."

Well, squeezing soybean oil must be extracted, but how to squeeze this problem...... Not really.

Zhang Xi didn't know, but Kou Feng did.

"But it's the same as that flax seed oil extraction?!" Kou Feng asked.

"Hu Mazi?!" Zhang Xi was slightly stunned, a little overwhelmed.

What the hell is a flax?!

Kou Feng didn't think it was strange, the scholars of this year and month didn't know Hu Mazi was not a big deal.

Although the scholars of these years have not yet advocated empty talk as much as they did in the Wei and Jin dynasties, it is not a big deal not to know about this kind of thing at the bottom of society.

Kou Feng took advantage of the situation to give Zhang Xi a popular science.

This flax seed is a plant brought back by Zhang Qian's envoy to the Western Regions in the pre-Han Dynasty, which belongs to an important oil crop in this era and is a major source of vegetable oil.

And the way to extract oil from flax seeds is to squeeze it.

The only pity is that the introduction time of flax seeds is too short, and people don't know how to plant this thing effectively.

Don't think that the things that have been introduced for 200 years have been a long time, in this era when most people can't solve the problem of food and clothing, it is impossible to make the common people give up growing life-saving food and plant cash crops instead.

Even in later generations, during the Jiajing period of the Ming Dynasty, it was a national policy to change rice to mulberry and it was promoted by the state.

Not eating oil will make people's physical fitness decline, but if you don't eat, you will die.

But soybeans are different, soybeans have a very long planting history in China, from the beginning of the ancient pre-Qin era to the end of the Han Dynasty has been planted for thousands of years, and it can be planted from south to north, and it can also be used as food for famine relief when necessary.

If this soybean can really be extracted from the oil by squeezing flax seeds..... Kou Feng didn't dare to think about it.

"Sir, quickly go into the city with me to see the lord!"

As he spoke, Kou Feng stepped forward and grabbed Zhang Xi's wrist, and was about to drag Zhang Xi to see Liu Bei.

Zhang Xi was inexplicable, and he forgot about the text, and said stupidly, "No, what are you doing when you see the lord?!" ”

On the second day of the Lunar New Year, Liu Bei accompanied Mrs. Gan at home for the New Year, should we be subordinates so blind!

"Ah, sir!" Kou Feng was quite anxious, and said to Zhang Xi, "Sir, do you know how big a matter it is once the bean can be squeezed for oil?!" ”

Zhang Xi continued to look confused, and Kou Feng was anxious, and continued, "Today's oil is mostly from the fat of poultry and beasts, and if the bean can take oil today, it will be far easier to capture the ....... of birds and beasts."

Yes, I see, I get it.

The ancients realized the usefulness of oil to the human body for a long time, and they have been trying to obtain oil from nature.

The mainstream source of edible oil in this era is animal fat, which is basically obtained from cattle, sheep, pigs and other animals, which also creates a group of "meat eaters".

After all, people who can eat oil all year round must have much better physical fitness than people who can't eat oil.

Since the birth of human beings, we have never stopped craving oils and fats, whether they are vegetable oils or animal oils.

Previously, because of the relative convenience of obtaining animal oil, humans from ancient times to the present have mainly obtained animal oil, but the introduction of flax marks that the Chinese of this era began to seek access to vegetable oil.

But after all, flax seeds were introduced from the Western Regions for more than 200 years, and neither the planting history nor planting experience can be compared with the soybeans that have been planted for thousands of years.

Once soybeans can obtain vegetable oil, this is simply epoch-making for Chinese who are good at agricultural civilization.

"I see...... But can't go now! After Zhang Xi understood his intentions, he still refused and said, "I am not sure that this bean is extracted from oil, if I go to report to the lord now, I can't squeeze it out..... Wouldn't it disappoint the lord?! ”

Right, it's better to be cautious about this.

You can't give people hope and let them watch their hopes shattered.

Again, although Zhang Xi can indeed determine that soybeans can be squeezed for oil, but how to squeeze it, whether it is squeezed according to the so-called squeezing method of flax, this Zhang Xi really does not know.

Even, until now, Zhang Xi has not figured out what this Hu Mazi is.
