Da Hua'er blushed a little, and the tendons in her neck were tensed, but she couldn't say that Erhua was wrong. She is a little dumb, but not stupid, think about it seriously, Erhua's worries are not impossible.

Wei Jin didn't get involved in the two sisters' lawsuits, and she was now busy thinking about whether to come up with some tricks.

On this two-sided noodle pot helmet sandwich dish, there are already people who are pirated now, even if the taste is not very good, there are always people who are willing to buy cheap and convenient. What she wants to do is never to compete with others at low prices, but to lead the trend.

There is such a thing as a pot helmet in the north and south, and the difference is still relatively large. When you arrive in Chang'an, the soft dough cake with braised mutton and beef is a meat bun, but in the southwest, there is another kind of pot helmet that is different from this, but the taste has its own unique place.

Her mother's hometown is a famous place rich in pot helmets, and basically many southwestern people will think of that place when they think of pot helmets. Wei Jin has never done it, but he has eaten a lot, and he will do it, but the heat needs to be pondered.

The most important thing is that this kind of pot helmet is very oil-intensive, and her current strength is not enough to use a lot of oil casually, unless she can get rapeseed oil or soybean oil out.

The oil yield of soybean oil is much lower than that of rapeseed oil and peanut oil. However, in the current situation of grain production, soybean oil is the most cost-effective. Because the price of soybeans is really quite cheap, even if the oil yield of soybeans is not high, its cost is cheaper than rapeseed oil. And rapeseed oil is mostly liked and accepted by people in the south and southwest, and the smell of rapeseed oil is difficult to accept for people in the north and north and east China.

Now the cultivation of peanuts is not very extensive, and the use of peanuts to extract oil has never been heard of, Wei Jin does not know the price of peanuts in the market, so there is no way to compare the cost performance of the three.

Locals don't know how to eat vegetable oil, and it's already very enviable to be able to stir-fry vegetables with animal fat. And to be honest, in this day and age, animal fat is more satiety than vegetable fat.

But the problem is that the price of animal fat is high and the quantity is small, if only this single oil is used to make food, the price will definitely not be cheap.

As for how to extract oil from soybeans, Wei Jin has only heard of it but has not touched it himself. The poverty alleviation point where she is located has an old-fashioned oil mill with two oil presses, one for sesame oil and the other for soybean oil.

In this old-fashioned workshop, the oil extraction generally adopts the cold pressing and soaking oil method, and the modern factory will use high-temperature hot pressing in order to improve the oil yield, and the great difference in efficiency between the two has impacted the traditional handicraft workshop, so when Wei Jin went at that time, in addition to the sesame oil machine was still running, the soybean oil had been suspended.

She was curious at that time, and she also listened to the scientific and technological personnel of the Poverty Alleviation Office, and had a rough understanding of the extraction of soybean oil. Even so, the calculated cost should be lower than the refining cost of animal fat.

The plan is doable, but there is a conundrum ahead. How can she find the right craftsmen and make excuses for oil extraction?

This is not such a trivial matter as making food, and it cannot be explained by ingenuity.

Although Wei Jin is anxious to innovate, he is not stupid, and he will not hurt his mouth because he is anxious to eat hot tofu. While thinking carefully about how to refine the plan, she is trying to find other projects to expand her business.

At this time, Erhua popped out on her own, and she said that she could sell steamed buns at the same time.

Steamed buns are still the mainstream food of this era, those without stuffing are called white steamed buns, and those with fillings are called meat steamed buns. Erhua's kneading and dough skills are stronger than Wei Jin's, so she simply handed over this piece to the second sister to be responsible, and she specializes in how to adjust the filling.

Everything is the same, and whoever tastes better will sell more.

Wei Jin was born with a sensitive tongue, and she could taste it as soon as she tasted it.

asked her eldest brother-in-law to bring back a few meat steamed buns from the county town that were said to be particularly popular, and Wei Jin tasted them all, and she also had a number in her heart.

Unlike others, she knows how to make meat steamed buns, and she definitely has to make them, but she also plans to come up with a novel trick.

This pattern is actually a flower bun born in the Northeast. What she has to do is very simple, that is, knead the dough with vegetable juice, then add the dough of carrot juice, and stack it into three colors to make a delicate snack with white stamens, red petals, red leaf receptacles, and green. This kind of snack also has to be sweet and flavored with stone honey.

Such delicate dim sum cannot be sold casually, only customized. In addition, salt and pepper and chopped shallots are used to make salt-and-pepper flavored flower rolls, which are the same price as white steamed buns, but have a richer texture and taste than white steamed buns.

For the time being, there are only two kinds of stuffed meat dumplings, powdered vegetables and minced vegetables, but the taste in the minced vegetables and meat is better than that brought back from the county by her eldest brother-in-law, and even her eldest brother-in-law is full of praise for eating it.

With these things, her family's business is better again. even paid to rent the area of a shop in the bamboo forest of the Lu family and made a simple bamboo hut to sell food.

After more than three months of business, everything is on track, basically the number of daily sales has also been estimated, the prepared noodles are almost finely used, and the saltpeter ice is also used by her to keep the takeaway fresh.

Wei Jin's brain was working, so he specially asked Zhang Xiaosan to make a rattan box, make it into the form of a chain, and put it on the back of the donkey, and the boxes on the left and right sides were paved with shabby fabrics. Then place the set pots, helmets, steamed buns and other things in it. When the weather is hot, she also uses a bamboo tube filled with water and put it in the saltpeter-dissolved ice to cool it, and when the food is delivered, she puts the ice bamboo tube in the middle of the food to maintain the temperature in the box so that it is not too hot and the food spoils.

Zhang Xiaosan is honest and honest, and he is also a down-to-earth, capable and honest young man. He followed Wei Jin's instructions, and took on other tasks by the way when delivering food. He also asked Wei Jin to teach him to write his name and make his own bamboo pairs, so that more people were asked to deliver and order takeaways, and even asked his brother to help with him.

It was impossible for his family to buy another donkey, so his brother went to the town early in the morning to wait, but whenever someone greeted and sent something, the Zhang brothers wearing special overalls vests followed the process, and in just one month, the foundation was laid in the town, and there were even people who specifically asked them to help deliver things to the county.

In the past, this kind of thing was to ask the caravan to help send it over, and the large items were fine, and the small ones were urgent, so they either ran by themselves, or they had to spend a high price to find someone to send them on a special trip. Now that the brothers of the Zhang family have done this business, they also deliberately went to the yamen to prepare a case, and they are doing it as a legitimate livelihood, and the others will be willing to find them to run errands after calculating the cost.

The Zhang family has benefited, and they prefer to help the Wei family sisters every day, but whenever they get a roof to chop firewood or something, when the Zhang brothers make it for their own family, they help the Wei family to get it together. It's not that there is nothing in his family, and the people on the opposite side of Zhang are all kinds of envy, jealousy and hatred, and they also deliberately arranged that Wei Jin had a personal affair with Zhang Xiaosan.
