The black sugar in the jar Yunyi had only eaten it once, and he couldn't arouse any interest anymore.

He thought that the taste of this kind of black sugar should be similar to the brown sugar in his previous life.

But after tasting it, I realized that the two are not the same thing at all.

Not only is the color of those black sugars black and yellow, but they are not clean crystals like the brown sugar in the previous life.

In fact, when he bought sugar in the market, Yunyi also saw white sugar similar to his previous life being sold.

It's just that the quality of those white sugars is not very good, not only the color is yellow, but also there are a lot of impurities in it.

The most important thing is that the price of those white sugars is more than ten times that of black sugar.

So Yunyi finally chose the lower price of brown sugar.

Now that he is not used to eating, in line with the principle of not wasting it, Yunyi decided to use these black sugars to refine white sugar.

Yunyi only knows one method of making white sugar, that is, the yellow mud water sugar pouring method recorded in "Tiangong Kaiwu".

In his previous life, when he watched the CCTV cultural program "China in the Classics", he became interested in a plot of Song Yingxing, a famous scientist in the Ming Dynasty.

So after watching the show, I found the book known as the "Encyclopedia of Chinese 17th Century Crafts" and read it for a while.

And the sugar production process of this yellow mud water drenching sugar method is what he learned from "Heavenly Creation".

However, although the production process of this yellow mud water drenching sugar method is not complicated, it requires a lot of utensils.

Considering that he was just making a jar of black sugar, Yunyi finally chose the simplest charcoal adsorption method.

Put the brown sugar into water to boil and melt, then add charcoal to adsorb, and filter out impurities through a filter cloth.

This is repeated several times, and the black and yellow sugar water gradually becomes clear.

With the experience of refining refined salt just now, the little girl has calmed down a lot this time.

However, when she saw the white sugar gradually pouring out of the pot, she was still shocked and opened her mouth wide.

You must know that these white sugars, even those rich families, can not be eaten every day.

But now Yi Ge'er can actually use cheap black sugar to make expensive white sugar.

The price of these two is more than ten times different!

Looking at the white sugar in the pot, Yun Yi couldn't help but feel hot in his heart.

It seems that I have found another way to make money!

Before, Yunyi didn't dare to take soap out to make money, and that was because the Great Zhou Dynasty did not have soap.

Once this kind of thing comes out, and you don't have the capital to protect it, it's no different from Xiao'er Huaijin.

Not only will it not bring wealth to itself, but it will also cause trouble.

However, these are obviously much better than the white sugar on the market, so there is no need to have such concerns.

First of all, there is such a thing as white sugar, which is already available in the Great Zhou Dynasty, even if he makes white sugar with better color, it will not look abrupt.

Secondly, white sugar is a rare thing that only rich and noble families can afford, and the consumer group is very limited, so it will not attract much attention.

However, if you want to make money from sugar, there are actually several big problems that need to be solved.

First of all, if you want to mass-produce white sugar, you can no longer use the charcoal adsorption method to make it.

Not to mention whether the charcoal adsorption method can mass produce sugar, just the charcoal needed in the production process is a large amount.

In ancient times, due to the lack of chemical fertilizers, people often scattered plant ash into the ground as fertilizer.

So it's not easy to get enough charcoal quietly.

In addition, even if you use the yellow mud water drenching method to make white sugar, the raw materials are also a big problem.

With his current financial resources, it is estimated that it will be difficult to get raw sugar directly.

Therefore, the raw materials in the early stage must be based on black sugar.

However, once you purchase brown sugar in large quantities, it will definitely attract the covetousness of those who have a heart.

At that time, if someone spreads the news about his own scholars and businessmen, I am afraid that it will directly affect his future road to the imperial examination.

Finally, there is the most critical question.

Even if you make sugar in batches, if you don't have the right sales channels, it will be difficult to do this business in the long run.

After thinking about it, Yunyi felt that the business of making white sugar was promising, but he couldn't rush it.

"Brother Yi, it turns out that this is how the sugar came from?"

Although the white sugar in the pot had not completely dried up, the crystal sugar grains on the wall of the pot had already made Shen Youwei's eyes widen in surprise.

"Yes, white sugar is actually purified from raw sugar. Come on, how about a taste. ”

Yun Yi saw the little girl's apricot eyes wide, and couldn't help but laugh, and directly handed the chopsticks stained with a lot of sugar in his hand to the little girl's mouth.

The little girl's pretty face instantly began to turn red again, but she still couldn't hold back, and gently opened her lips and licked the sugar on the chopsticks.

"It's so sweet! There is no burnt or bitter taste of brown sugar. ”

As soon as the tip of her tongue touched the chopsticks, the little girl's eyebrows and eyes instantly smiled into peach blossoms.

It turns out that real sugar is only sweet!

"Eat more if you like, but remember to rinse your mouth after eating, otherwise the bugs will eat your teeth!"

Yunyi seemed to be coaxing a child, and couldn't help but rub the little girl's head again.

"Hmm."

The little girl hummed softly with a smile in her eyebrows, but her little face became even redder.

"I see that this kind of white sugar is also sold in the market in the county, and when I am busy for a while, I will see if I can find a suitable way to sell it."

"If there is no problem with raw materials and channels, we can treat this as a regular business."

"Let's do it secretly in the early stage, and when I pass the Xiucai exam, I'll go to the house to buy a servant and come back."

"When the time comes, these business matters can be handed over to the servants to take care of on my behalf, and I can continue my studies with peace of mind.

After listening to Yunyi's plan, the little girl's eyes were full of brilliance for a while.

After cleaning up the sugar in the pot, Yun Yi was already hungry.

So, the two of them hurriedly made lunch together.

Two bowls of white rice, a plate of stir-fried greens in lard.

Although it was simple, the two of them ate it very sweetly.

After lunch, Shen Youwei began to wash the dishes and chopsticks in the kitchen.

And Yun Yi used a bamboo basket to chill two bowls of white sugar water in the well, and then Shi Shiran came to the desk and read "The Law of the Great Zhou".

……

At the same time, on the village road not far from Taoyuan Village, two horse-drawn carriages were swaying towards the village.

Perhaps due to the hot weather, the two tall horses were both listless at this time.

Since there were no pedestrians on the village road, the curtains of the carriages were rolled up to keep them cool.

In the carriage in front, an old man in a Confucian shirt and white hair was sitting in it with his eyes closed.

Although there was sweat oozing from the old man's forehead, his demeanor was quite peaceful.

In the carriage behind, two sixteen or seventeen-year-old girls were shaking the fans in their hands weakly.

"Sister Qingyun, on this hot day, why do you have to follow your grandfather to such a poor country?"

The girl, who looked a little younger, was complaining against the carriage with a helpless face.

The little girl's voice was sweet and lazy, and her appearance was pure and lovely, which was somewhat similar to the old man in front.
