Yao Lao took the opportunity of collecting medicine and took Jiayi to find the salt mine. Jia Yi didn't say anything in his mouth, but he was still quite moved in his heart.

Neither of them is a person who is good at expressing emotions, and Jiayi usually says some sweet words to make Yao Lao happy, but he still can't say anything that is too numb.

As soon as Jia found salt, he wanted to make some refined salt to sell, and the last time he saw the so-called snow salt in the store selling so expensive, he had this idea. Although the salt industry in the entire territory is controlled by the lord, if he wants to officially insert the salt industry, it is estimated that he will be swallowed by the lord's entire concubine.

It's just that now he doesn't want to make salt and sell it on a large scale, he just wants to do some high-end manual work to get some pocket money. It's just that the technical benefits of making refined salt are too great, and how to sell the salt has to be carefully considered.

In fact, Jia Yi thought about selling wine, because although wine is also controlled, it is much more relaxed than the salt pipe. In addition, there is a tradition of moonshine brewing and drinking it by yourself, and there are also people who inherit their own unique craftsmanship, and the sake brewed is very marketable. Besides, Yao Lao seems to know the tavern owner, and the brewed wine has a good chance to be sold directly in the tavern, without directly entering the market, which is a lot less troublesome.

It's just that he says a thousand things and ten thousand, winemaking costs money, buying grain, and winemaking also requires technology, and his only advantage is that he knows that distillation can make high-grade liquor. And then the high alcohol costs more than 10 times, can it be sold for more than 10 times the price? Are you sure that there are many people who like it? It takes time for people to receive it.

Finally, steaming wine requires tools and money, if the seal is not good, it will be a waste of food if it runs out, and after thinking about it, it is easier to make salt, just filter it with some charcoal, and it is more operable, and he can do it himself.

After finding the salt, Jiayi's task today has actually been basically completed. He loaded the salt in the small half-basket and prepared to go back.

"Jiayi, what are you doing here?" Seeing that he had filled a large piece of salt, Yao Lao took the initiative to go back and asked.

"Huh?" Jia Yi felt that Yao Lao was asking a little strangely, shouldn't he go back when he found the salt? ”

"We're here to collect medicine, and we're going to teach you how to identify the herbs in the wild, have you recognized them all? Yao Lao said to him, there is no doubt.

He remembered that Yao Lao told him that he came out to collect medicine today, not to look for salt mines, and that finding salt mines was just incidental, although Yao Lao's route was very purposeful and went straight to the salt mines, but for Yao Lao, medicine collection is the most important thing.

Jia Yi carried the salt mine on his back and the herbs collected on the road, and continued to walk around the mountains behind the medicine elder, looking for medicinal materials. The things he was carrying on his back were really not light, especially the large salt mine. It was a relatively pure salt mine he had selected, with a grayish-brown surface of mud mixed with some cloudy, crystal-like transparent lumps of salt.

It can be seen that the quality of these salt mines is not high, and there are many impurities in them.

I don't know if Yao Lao is because Jia Yi is too concerned about the salt mine, and he has been asking for leave to find salt recently, and he has neglected Yao Lao's pharmacist skills, so he has the heart to teach Jia Yi a lesson, and he does not take the initiative to help Jia Yi carry a heavy salt. Jiayi didn't ask for it, after all, the body is an adult's soul, and the heart of respecting the old and loving the young still exists, although it is now a Zhengtai body.

In the evening, the two returned to the village, and the sun on the horizon reflected in the river, as if the river was on fire.

Erica, the mother at home, has already cooked the meal, and the work in the field has come to an end for the past two days, and Erica has time to come back to cook first. Although Jiayi's cooking is more delicious, Jiayi came back late today, so he had to eat before the sun went down.

In a few days, it will be time to plant beans, and the field here is rotated, and the field is divided into two fields, one is planted with wheat, and after the wheat is harvested, the beans are planted, and the other field is left fallow for a year, and in the winter the other field starts to grow winter wheat, and now the land is fallow, and it has been rotated like this.

The beans here are not soybeans, they are larger than soybeans, the surface is wrinkled, not as smooth as soybeans, and the germ part bends outward with a hook. The taste tastes a little chestnut, and it is thoroughly boiled and tastes noodles.

I don't know if this bean can make tofu, Jia Yi likes to eat tofu, and I'm ready to have time to make some to try it myself, if this bean can't make tofu, it's a pity. However, the theory is that the soybean protein is separated from the water due to the agglomeration of the gelling agent. Theoretically, as long as the beans are rich in protein, you can make tofu.

This bean should be rich in protein, right?

After returning home, Jia Yi was tired, the soles of his feet hurt a little, and his knees were very sore, after all, he walked for an afternoon with nearly 10 pounds of things on his back, and he was still young.

He left the herbs at his home and returned home with the salt he had brought back.

"Kaichi, what did you bring back?" Erica asked strangely, looking at the salt cube that Kaichi had brought back.

"Mom, this is salt, I found it with the teacher. ”

"This salt is inedible and poisonous. Erica hurriedly said, afraid that Jiayi used this salt when cooking, "It turns out that some people in the village wanted to save money and picked this salt in the mountains to eat, and then the family was poisoned to death." So people knew that there was salt in the mountains, but they had to go to the town to buy salt and eat it. ”

"The salt in the town is boiled from the water in the salt lake, and it is not poisonous. It is said that some mountain people in the mountains to the east have discovered salt wells, and the water from the wells is salty, and salt can be boiled. ”

"Ah, won't they get rich, not only will they not have to buy salt, but they will be able to sell it. ”

"No, the salt well was taken away by the lord, and the salt well can produce good snow salt, and after the lord knew about it, he sent a knight to lead the troops to take it away. ”

But the salt merchant in the town said that the snow salt there was brought in from other places. ”

"I don't know, it seems that there were some thieves behind it, and then the salt well was abandoned, and no one can find it again. Hearing that the rate of salt production was too slow, the lord gave up. ”

"Okay, let's not talk about that. You know, Kaichi, don't use this salt for cooking. ”

"I know, mother, how can you tell if it's good salt or poisonous salt, and what if some black-hearted merchant sells it as lake salt?"

"If you look closely at the mineral salt, there will be dirt in it and it will turn gray, while the lake salt will be yellow and there will be sand in it. This is actually not easy to distinguish, the main thing is to taste, the mineral salt is a little slightly bitter, the lake salt is not, only salty. In fact, the most reliable thing is to buy it from the shop in the town, although the lord took away all the places where salt can be mined, but he guaranteed that the salt in the town is no problem. ”

Erica stared into Kaichi's eyes and spoke to him carefully.

"Oh, I know Mom, I'm not going to mess around. Kaichi assured his mother.

......

In the evening, after dinner, Kaichi melted the salt cubes in the water, and the water immediately became turbid. He dipped his hand in a little salt water and tasted it, and it did seem a little bitter.

He put the melted brine in the kitchen and prepared it to sit overnight to settle down. It's a pity that there is no alum, otherwise it can better remove impurities from the water.

After thinking about it, he found a few more pieces of charcoal, smashed them, and added them to the salt water.
