After a while, the two sisters held a bowl of hemp food directly in the kitchen, enjoying a moment of tranquility and serenity, the soft and sweet taste of sweet potatoes burst out in their mouths, and Yunzhu's eyes lit up.

"Zhao San! I know! She held half a bowl of sweet potato wedges and was pleasantly surprised.

Sweet potatoes are bloated after eating too much, so later generations processed them into sweet potato starch, sweet potato syrup, and sweet potato flour skin...... Yun Zhu carefully recalled the tutorials he had seen in his mind, and talked to Zhao San about the production process with comparisons.

Zhao San, whose eyes became brighter and brighter the more he listened, would almost jump up if he didn't hold a bowl in his hand, whether he bought maltose into sugar or bought wheat to make it himself, it would be expensive.

If it's a sweet potato...... Seeing that Liu'er was reasonable, she just regarded it as a method in the Guogong Mansion, and agreed: "Listen to what you say, the syrup can be tried, but the two of them are laborious, when your brother-in-law comes back, we will try it tomorrow!" ”

Zhao San replied so firmly, but Yun Zhu didn't know the bottom in her heart, she had only read this method in a book before, and the specific situation depended on the actual operation, so she simply didn't do it and said bluntly: "It's still early now, why don't we try it first, and take the finished product, so that you can convince your brother-in-law."

If it doesn't work, we can also make dried sweet potatoes, which are not wasted. ”

After a thousand words, it is better to get started, Zhao San looked at the direction of the city gate, and saw that the sun was still there, so he nodded: "You are right, it sounds like it just costs some firewood, you wait for me." ”

Zhao San struggled to remove the hay in the firewood room, moved a dilapidated wooden basin, and a small cellar entrance appeared underneath, looking at the piles of sweet potatoes inside, Yunzhu had to admire Zhao Laosan's ability to live.

"The sweet potatoes were put out like this, but they sprouted in half a month, and I thought, when we went up the mountain in the past, those sweet potatoes that fell in the stone holes, even if they became dry, did not sprout, and they must be because they did not see the light of day.

Later, I asked your brother-in-law to dig this cellar, and the soil dug out was all cushioned in the yard, and the neighbors didn't know that we had a cellar! Zhao San bent over and half-fell into the cellar, constantly throwing sweet potatoes out, and Yun Zhu had to pick them up behind him with a wooden basin.

It is very common in the north to have cellars, and basically every peasant family has them, but it is a rarity in the city.

In the city, digging the cellar is a technical job, it is easy to collapse when it is big, and it is impossible to put anything down when it is small, so most of the cellars in the city are funded by several households, and special craftsmen are invited to dig the cellars, and then someone takes turns to guard the food at home, so that things can be protected.

Second, if the poor family has a cellar, and when the master's family goes out to beg for a living during the day, the unguarded cellar is like a candle in the dark night in the eyes of the thief, and the professional has passed by for 30 years.

However, Zhao San's method is extremely clever, digging a small cellar, and then covering it, anyone who comes in and sees this family with four walls will not think that there can be so many things stored in the house.

"Enough is enough!" Seeing that the wooden basin was half-loaded, Yun Zhu made a sound again and again, just make a sample first, these are enough.

To make sweet potato syrup, the main ingredient is that the sweeter the better, now the sweet potato production is large, cheap and high-quality, just suitable for some fine processing, but it is a fire and labor, but the firewood in the city is also an expense, watching Zhao San pick up the broken hay on the ground one by one and put it into the stove, Yunzhu suddenly felt that he was a little reckless.

If you can't make syrup, sweet potato mash drying is also a ration.

But the firewood costs real money to buy, the Guogong Mansion is rich, and the good silver filigree carbon in the pantry is burned all day, and no one has ever cared about the cost, but what are the conditions of the Zhao Sanjia? The kitchen is next to the firewood room, and the stacked dry firewood is only a small bundle, mostly some messy hay, and Yunzhu's hands hesitate to peel the skin, "Firewood is expensive, right?" ”

Poof

Zhao San hid his face and smiled, and couldn't help but snort at her: "You are still so small, not expensive, we are close to the city gate, there are mountains and forests two or three miles out of the city, although it is said that the forest with the owner is not allowed to collect firewood, you can cut some hay and twigs, it is easy, don't worry, ask your brother-in-law to go two more times." ”

Liu Ping created some space for the two sisters, and when they saw that Yunzhu was there, they went out silently, and Zhao San didn't leave him, but silently put a big bowl in the pot when he ate hemp food, and burned it on the stove with the residual warmth.

Seeing the juice of the boiled sweet potato chips draining out of the juice and the juice slowly boiling in the pot, Yunzhu found a bamboo, peeled off a layer of bamboo skin, carefully smeared the remaining sweet potato puree evenly on the bamboo, and baked it carefully in a place where there was no open flame at the stove, and waited until the sugar water in the pot was drawn.

The two of them tossed all the hay in the firewood room, and only the bundle of dry firewood was left alone, which would cover the entrance to the cellar.

As soon as Liu Ping, who came back with a bundle of hay on his back, entered the house, he rubbed his eyes, stared at Zhao San in disbelief, and asked what did you do?

He wanted to ask if you were taking a bath at home, and remembered that his sister Yunzhu was only a half-grown girl, so he changed his words: "If the firewood is not enough, I will go and pick up another bundle to come back." ”

Zhao San didn't answer directly, but stuffed the chopsticks dipped in syrup into Liu Ping's mouth: "Lang Jun, you taste what this is first!" ”

"Sugar! What a sweet sugar! Liu Ping was happy at first, and then his brows furrowed again, "Didn't we say that this syrup is time-consuming, laborious and costly, but it doesn't make much progress, so don't you do it in the future?" ”

Looking at the empty firewood room, and then looking at the bowl of red brown syrup resting on the kitchen stove, looking at Zhao San's expectant eyes, Liu Ping was energetic, complaining a lot in his heart, but he tried his best to be tactful, for fear of losing Zhao San's face in front of his aunt.

He was a man, and he was not to be as irritable as an outsider to his wife.

"Brother-in-law, try this again." The tender white little hand handed a piece of yellow-brown fruit in front of him, Liu Ping asked his wife with his eyes to take it, and he didn't dare to send it directly to his mouth, it was really good-looking......

The dried sweet potatoes are a little burnt, because Yunzhu has insufficient ability to control the fire, so he doesn't blame the sweet potatoes. Liu Ping put it on the tip of his nose and sniffed lightly, the paste was sandwiched with a burnt and sweet taste, and after confirming that it was food, the big man who hadn't eaten lunch couldn't help but take a bite and chew it carefully in his mouth.

The expression of surprise was even more shocked, and he suddenly stuffed the remaining half into his mouth: "This is a sweet potato?!" ”

Looking at the two girls standing in front of him, one big and one young, waiting for his comments with an expectant face, Liu Ping had never read a book, and couldn't say anything flowery, so he just nodded again and again: "This sweet potato candied fruit is good, and this sweet potato syrup is also good, not bad." ”

"The hay is not burned, although a room of grass is not worth the money, how many sweet potatoes are used?" It is worthy of being a merchant, in a word, straight to the core output ratio.

Zhao San rummaged through the bamboo basket containing dried sweet potatoes, intending to find a piece of dried sweet potatoes that looked like Zhou Zheng, and said while picking it up: "About ten catties of sweet potatoes, I only have this bowl of syrup, but I have made a lot of candied fruits, and if you try it again, you may be able to sell it?" ”

Liu Ping listened carefully to the production process of the two sisters, although it is a meticulous job, but the cost is quite low, now two big money in the market can buy five or six catties of sweet potatoes, and ten catties of sweet potatoes plus some firewood, you can get more than a pound of syrup, and there are so many dried sweet potatoes.

Compared with the high cost of mainstream maltose, this sweet potato sugar is a huge profit.

Thinking about the key clearly, Liu Ping got up and bowed deeply to Yunzhu, and said solemnly: "Sister, there are many offences in the first, Liu Ping is here to compensate my aunt first!" ”

Ignoring Yunzhu's repeated wave of his hand, he took the hemp food handed over by Zhao San and put it beside him, and hurriedly asked: "My aunt is smart, I won't go around in circles, I am walking the streets and alleys now, I have never seen this sweet potato candy, I don't know if my aunt is willing to sell this craft to me?" ”

There is no sweet potato syrup in Beijing?

Yunzhu was stunned for a moment, and then remembered that this seemed to be a practice that arose first from the south, and now it has not yet been transmitted to the capital, so he thought: "This is not a new craft, the master of the fine and the meal said that you can't taste it a few more times to figure out the key, you now mention trading, I have a new way, just see if my brother-in-law is willing to believe me." ”

The three of them exchanged heads, and Liu Ping was even more amazed, and almost showed a respectful look to Yunzhu, is this everyone's maid? Thinking about it again, I still vaguely looked down on Yunzhu in slavery, and now I just want to slap myself twice, I can't read Ding, I can't read Ding!

Yunzhu didn't hide her selfishness, and when Liu Ping patted her chest and shared her net profit after packing the ticket, she racked her brains and talked about the sweet potato flour skin and sweet potato starch with the husband and wife.

At the moment, no one expected that Liu Ping would be able to solemnly hand two hundred taels of silver to Yunzhu in the coming year.

The merchant also has a business word, and his sensitivity to the market is far greater than that of the three Zhao sisters, Yunzhu mentioned the sweet potato flour skin, and he immediately thought of the signature dish in Huixiang Building, vegetarian turtle.

Liu Ping once sold a mill in front of Huixiang Building, that day the sky was dark, the mountain rain was coming, the child who bought the mill and drank the music struggled to pick the windmill on the child, the windmill was just a paper folded thing, worthless and afraid of the rain, so he simply gave the child away.

The child's elders saw that they returned with a full load, and the etiquette was thoughtful and rewarded him with half a bowl of vegetarian turtles, listening to the little guy's colorful description of how the vegetarian turtle is a signboard in Huixianglou, and how it is unique in Beijing, even the monks of Huguo Temple outside the city have sent people to come to study, and Liu Ping, who was hungry, ate the vegetarian turtle in the blink of an eye.

It's really delicious, if this sweet potato flour skin really tastes like my aunt said, wouldn't I ......

It's been posted!

He carefully recalled the color and fragrance of the turtle, and when he heard Yunzhu say that he could use bamboo charcoal powder to dye a black shape, and it also had the effect of clearing heat and detoxifying, he only wished that he could also sell himself into the Guogong Mansion.

But seeing that the sky was full of red clouds outside, many officials were already standing at the door and knocking on the door.

Zhao San, who got carried away by the hearing, remembered that Liu'er said that she needed to go back when it was dark, and she couldn't help but feel sad again, she carefully described the goose egg face, and held back her grief and said: "I heard that there are many rules in other people's homes, and it is not easy to come out for a trip, let's see you next time, I don't know when, you have to be good, good, we will always meet again." ”
