After entering the hall, Shang Xiucai didn't ask the three of them, but just asked Ah Jiu to go to the mule cart to fetch the four treasures of the study he was carrying, and one of them gave them a piece of paper, a pen, and a little ink, and said to them: "Write down what you think you learn best." ”

"Huh?" Gu Dewang was stunned: "Didn't Master Xiucai ask?" ”

The mother said that the Xiucai master would only ask him a few questions, and he just answered according to the teaching, why did he change it to writing? Let him write what? He never went to private school.

Village Chief Gu has only gone to private school, Gu Dexing. Gu Dewang was only eight years old, and he was only six years old when he was affected by the drought in the northwest for two years, and he had never gone to school at all, but only learned a few words with the village chief Gu and read the three-character scripture for a few days.

Shang Xiucai smiled and didn't reply, just left Ah Jiu behind and watched them write. He himself said to the third grandfather and Gu Dashan: "Third Uncle Gu, Brother Gu, your tofu is a fresh food, Wen Yuan has always been very curious, I don't know if I can go and see it?" ”

The third grandfather and Gu Dashan wanted to befriend Shang Xiucai, so they naturally readily agreed.

They went to the courtyard of the Luo family first, and after watching the grinding beans, Shang Xiucai pointed to the white soybean milk flowing out of the grinding plate and asked, "This is soy milk?" ”

The third grandfather smiled and nodded: "Yes, but these are soy milk with bean dregs, after filtering the bean dregs, then put them in the pot to cook, braised them into bean curd, and then compact the bean curd to become tofu." ”

"What about soy milk? Can you eat it with sugar after cooking? Shang Xiucai asked, he didn't ask about the stew, although he was curious about how this tofu was made, he knew that this was the Gu family's secret recipe, and he couldn't ask.

The third grandfather said: "The soy milk should be diluted with water, if you drink pure soy milk, the taste is too strong and it is not delicious." ”

"I see." Shang Xiucai suddenly realized, looking at Gu Damu and Gu Dalin brothers pushing the grinding plate to grind beans, looking very hard, and secretly wrote down this matter.

And he said, "How much tofu do you want to make this day?" There is only one grinding disc, I'm afraid it's not enough. ”

The third grandfather said: "It's really not enough, we are planning to buy stones and come back to make a stone mill." ”

Originally, I was going to do it some time ago, but when I encountered the Lu family's affairs, it was delayed.

When Shang Xiucai heard this, he looked at Gu Dashan, who was silent, with a surprised face, and said with admiration: "Brother Gu can also do stone grinding, this is not a small skill." ”

Gu Dashan smiled honestly: "What kind of craftsmanship is not craftsmanship, it is all work that has been done before." ”

He was kicked out of the house by Mrs. Gu since he was a child, and he did all kinds of work as a carpenter, mason, well digger, and stonemason.

However, Shang Xiucai said: "There is an abandoned stone mill in my old house, let Ah Jiu send it to you tomorrow, and you don't need to buy the stone mill again." ”

It takes a lot of effort to polish a new stone mill, and when the Gu family is short of manpower to make tofu, he might as well give one to their family.

When Gu Dashan heard this, he hurriedly waved his hand and refused: "No, no, this stone mill costs a lot of money, Brother Shang, you have already given a lot of gifts today, but you can't give it anymore." ”

Shang Xiucai said with a smile: "Brother Gu, that stone mill has been in the old mansion for almost twenty years, you don't want it, and you can throw it away somewhere, so don't postpone it." ”

Gu Dashan had no choice but to respond.

Gu Damu and Gu Dalin brothers listened to it next to him, and they were very useful, this Shang Xiucai did not have the frame of the county lieutenant's son-in-law at all, and he was very approachable.

Gu Dagui and Gu Dafu were filtering soybean milk on the side, and when they saw Gu Dashan approaching, they hurriedly gave him a look, and when Gu Dashan came over, Gu Dagui asked him in a low voice: "Brother Dashan, my mother-in-law didn't make trouble for your family, right?" ”

Last night, Chen said that he would take a few children to let Shang Xiucai take in apprentices and study with Shang Xiucai for free. He scolded her severely, saying that she didn't take advantage of it enough.

Chen answered him at the time and said that he would not mention it again, but as soon as he and his eldest brother came to the courtyard of Luo's house to do work, she took her four children and ran to Brother Dashan's house upside down. He saw it and wanted to chase after it, but he was afraid that it would be too ugly, so Shang Xiucai would hate them, so he endured it.

But in my heart, I really didn't worry about the Chen family, for fear that she would offend the county lieutenant's son-in-law and bring trouble to them.

Gu Dashan said: "There are three aunts here, it's okay." ”

Shang Xiucai heard their words and didn't say anything, the peasant family is like this, and it is also for the future of the child, but whether to accept the apprentice or not, it is up to him to decide.

Shang Xiucai walked around the courtyard of the Luo family, chatted with Gu Damu and Gu Dalin brothers, Gu Dafu and Gu Dagui brothers for a while, and then turned back to Gu's house to see the soybean milk boiled in the kitchen, as well as the bean curd separated from the pulp and water, and the pressed tofu.

"It's really amazing, the beans are so grinded, boiled and pressed, they have become a new food." Shang Xiucai sighed.

Gu Jinli was talking to Cui's, Gu Jinxiu, and Gu Yumei with Jiang's mother and daughter, and when he heard this, he got up and left, came to Shang Xiucai's side, and took the opportunity to say: "In addition to making tofu, beans can also make a lot of food, such as soybean paste, bean sprouts, soybean oil, and a soy sauce that tastes similar to the fresh sauce. ”

When Shang Xiucai heard this, he was shocked, and hurriedly asked Gu Jinli: "Can you make oil and fresh sauce?" It's true? ”

The sauce is a sauce made from pickled meat, and the cost is very high, so it can be sold for a small pot of silver or two on the market, and only the wealthy people can afford to eat it.

But the soybeans only sell for three dollars a catty, and if you can make soy sauce that tastes similar to the soy sauce, it will be really ...... He couldn't imagine what a sensation the soy sauce would cause.

And that soybean oil.

In Dachu, there are only two kinds of oil, one is meat oil for eating, and the other is pine oil for lighting. And Da Rong, I heard that there is a kind of ghee made of cow and goat's milk, he has never heard of soybean oil, this soybean can really be made into soybean oil, it is really a good thing for the country and the people.

Shang Xiu knew that this matter was too big, so that his current ability couldn't protect these two things at all, so he said to Gu Jinli: "Good boy, who else have you told about this?" ”

Gu Jinli said: "Uncle Shang, don't worry, the matter of soybean oil and soy sauce is known to a few of us here." ”

She understands the truth of Huaiyuqi's sin, so she will not make everything she can do at once, but the same, and she will do it if she can shelter this kind of thing.

Before, she just wanted to make tofu, but it was because she met Shang Xiucai and knew that Shang Xiucai was the son-in-law of the county lieutenant, so she wanted to make fresh sauce and soybean oil.

With County Lieutenant Jiang's ability in Tianfu County, he should be able to protect these two things and prevent them from causing them to be killed.

Shang Xiucai listened to it, and then he breathed a sigh of relief, and he asked Gu Jinli about the soy sauce and soybean oil method again.

Gu Jinli said: "The production time of soy sauce is longer than that of fresh sauce, and it takes half a year to marinate the fermented soybeans before it can be made into soy sauce." As for the soybean oil, the production time is relatively short, but the process is complex and requires a lot of manpower to make. ”

Stir-fried beans are very simple, but squeezing oil is very laborious, and you can't squeeze the oil manually without more than ten laborers.

"And ten catties of soybeans can produce more than one pound of soybean oil, and the cost is very high."

"However, soy sauce is much better, although the fermentation time is long, but one pound of soybeans can produce two pounds of soy sauce, and it is not troublesome to make, it is very cost-effective."

Gu Jinli explained all the pros and cons of soybean oil and soy sauce.
