Beans are a kind of miraculous food, and many kinds of foods can be derived from simple biological and chemical reactions.

There are many members of the family of soy products, among which soy milk, tofu, and bean sprouts are the three most widely used.

In the kitchen of the Chen family, the experiment of brine tofu is still ongoing, and it is close to success, but it still lacks some effort.

The tofu is either too tender or too old, and the amount and timing of the brine need to be reconsidered.

On the other hand, the sprouts have made progress first.

Bean sprouts can be traced back to 2,000 years ago, but they have been ignored by the ancients due to various reasons such as technology and eating habits.

Like tofu, it has been a food that has not flowed into the stream for hundreds of years.

It was not until the Song Dynasty that it became the mainstream vegetable on the table, and together with mushrooms and bamboo shoots, it was known as the vegetarian umami tribal.

Alas!

It is no wonder that the ancient society developed slowly, and there was no major progress in 2,000 years.

In terms of "eating", the fundamental human need, they lack the spirit of exploration and discovery, improvement and optimization, and can they still be expected to innovate in the disciplines next to them?

Chen Yu sighed while carefully serving the bean sprouts.

After soaking, the beans are placed in a perforated urn and placed next to the stove, where the residual heat from the fire is just right to provide the right temperature.

In the cold winter, if the temperature is too low, the beans will not germinate at all, but if the temperature is too high, the half-cooked beans will completely lose their vitality.

Then there is water, the second most important element of plant germination, which must be just right.

Too little is not enough to guarantee growth, and too many beans will rot directly.

The aged fish that sprouts for the first time carefully serves an urn of beans like taking care of a child, changes the water to control the temperature, and takes care of it carefully.

Finally, wait for the buds to break out of the shell and gradually grow.

Bean sprouts, it's done!

Let this thing come out as soon as possible, and it can be regarded as benefiting the taste buds of the people of the Tang Dynasty!

……

The bean sprouts got off to a good start, and the brine tofu experiment went a lot smoother.

On the Nth attempt, I finally pressed out the tofu that was just right for the old and tender.

Chen Yu cheered, couldn't wait to cook fried bean sprouts and spicy tofu, and came another bowl of bean curd steamed buns, these days the bean porridge is really a little tired of drinking.

Cooking stir-fry in Datang is not an easy task.

Restricted by iron-smelting technology, the thick iron pot is heated slowly and unevenly, and the word heat is impossible to talk about.

It's good enough to be able to cook two dishes, but as for the taste, it can only be considered barely.

There are tofu and peppercorns, but the taste of dogwood is too different from that of chili pepper, and spicy tofu can only be regarded as a defective product, which is far from the authentic taste.

Rao is so, the family still eats very deliciously, and is full of praise.

"It's better than it's delicious." Mother Chen did not hesitate to praise words.

Is it that good?

Chen Yu felt that it was all emotional and overpraised.

How could a mother from a poor family easily eat delicious food? Could it be that his family used to be rich and noble?

Chen Yu couldn't help but have a doubt in his heart.

Chen and Xu Er couldn't help but feel strange, how could Xiao Yu'er, who never entered the kitchen, suddenly have such superb cooking skills?

Could it be that he also learned from that mysterious old man with white beard and white hair?

……

The technology of brine point tofu tends to mature, and a series of soy products such as tofu skin, dried tofu, and bean curd will come into being, which is only a matter of time.

However, Chen Yu doesn't want to spend so much effort for the time being, the family is living a tight life, and a lot of beans have been wasted in the past few days of experiments, and the granary is almost bottoming out.

In order to avoid starvation for the whole family, the first priority is to monetize the invention as soon as possible.

For this reason, Second Uncle Xu asked Li Zheng Laogen for help.

Fanchuan is not far from Chang'an, and there are many vegetable farmers on both sides of the Weihe River, planting vegetables to supply Chang'an vegetable market.

Ju'anli is no exception, and in order to facilitate the collective sale, Li Zheng often comes forward to deal with vegetable vendors on behalf of the villagers.

Therefore, Uncle Lao Gen is very familiar with the Chang'an vegetable market.

Selling vegetables, naturally you have to ask him for help.

Li Zheng Lao Gen was originally strange, in addition to pines and cypresses in winter, it is difficult to see green, can there be vegetables to sell in this season?

There are lotus roots in the silt of the Weihe beach, but on this cold day, unless you don't want to die, digging lotus roots in the ice water barefoot is simply looking for death.

Li Zheng, who was full of curiosity, went to the Chen family to take a look and couldn't help but be surprised.

A basket of bean sprouts, one by one, is crystal clear and tender, with two yellowed bean pastes, which looks particularly eye-catching.

Bai Shengsheng tofu is even more unseen, not like an ordinary thing.

After tasting the two more foods, my eyes lit up.

"At this time, the royal hot springs in Lishan may not have green vegetables. The bean sprouts are so tender and fresh that they will definitely sell for a good price when they are brought to the market.

And this tofu, so fine, it must be the food that only rich and noble families should have! ”

Li Zheng Laogen's rhetoric may be a slight exaggeration, but it also shows one point - scarce things are expensive.

Then, the price must not be lower.

Chen Yu said with a smile: "Then there is Uncle Lao Laogen, how about the same uncle go to Chang'an Vegetable Market?" ”

"Well said, well said!"

Lao Gen agreed very happily.

The heavy snow has not stopped for days, and the weather is even colder than before, which is rare for many years.

People froze to death in almost every village in the surrounding area, with the exception of Juanli.

Thanks to the work of the warm kang, the whole village is warm and healthy, and all of them are alive and well, comfortable and comfortable. When the officers who came to patrol Chang'an County saw it, they were amazed, and they must have been praised by the county order when they turned around.

This is all the credit of the Chen (Xu) family's uncle and nephew!

The villagers also learned the craft of changing the stove from their uncle and nephew, and went out to collect work to make money, and their own son was one of them, and he has been making a lot of money recently.

In a famine year, a few extra dollars can save lives.

This is all thanks to Chen Yu, as a direct beneficiary of Li Zhenghe, how can he not be grateful?

A little bit of selling vegetables is not a problem at all.

What's more, Chen Yu has made it clear that he will not let him run in vain.

Li Zheng Laogen and Second Uncle Xu went to Chang'an with a basket.

Before leaving, he swore an oath: "Don't worry, I have an old friendship with the vegetable market in the West Market, and I am sure to sell it at a good price, and you can wait at home with peace of mind." ”

Chen Yu originally wanted to go to Chang'an City for a walk, but Second Uncle Xu was tired after thinking about his injury. The road was covered with snow and was slippery.

Fan Chuan said that he was on the outskirts of Chang'an, but he walked more than ten miles to the Mingde Gate due south, which is not counting the distance from the city gate to Xishi.

Coming and going for dozens of miles, relying on two legs, thinking about Chen Yu retreated.

In those days, I didn't walk much in the mountains, and the chilblain wound on my feet only scabbed, and I didn't dare to toss at all.

It's just a little thing, Second Uncle Xu and Li Zheng Laogen will definitely be able to do it.

Chen Yu saw them leave, so he sat at home and waited for good news.

……

Xu Er and Lao Gen carried the burden, walked all the way through the snow, and entered Chang'an City without waiting for noon, and went straight to the West Market.

They entered the West Market with their front feet, and a man dressed in silk and satin and housekeeper also entered the West Market with their front feet, and hurriedly walked into a large restaurant with carved beams and paintings......
