In the afternoon of the same day, Wang Song had already bought all the things he had purchased, among them, there were hundreds of catties of plate oil, which was the material for making soap, and it was the only large amount of oil that Zhao Xin could find at present. Pen, fun, pavilion www. biquge。 info

Plate oil is a good thing, when vegetable oil has not been popular in the world, this is the only meat and stir-fried oil for ordinary people, used to increase the taste of food, the general farmer, when cooking, do not dare to multi-faceted, often use a small wooden board or a small wooden stick, just rip a little.

During the Northern Song Dynasty, stir-fry was not yet popular, and ordinary people used more cooking methods to cook, and fat was more used for seasoning, so that the soup or dish tasted better.

But in Bianliang, those big hotels headed by Fan Lou have begun to stir-fry vegetables. Stir-frying is a unique skill for skilled masters, and the emergence of vegetable oil and the application of some oils and fats have made this method begin to appear, with richer taste and more excellent taste, especially for foods such as green vegetables, stir-frying is the root of making it to a higher level.

In this era, in the big hotel, the price of a plate of fried vegetables is much higher than that of ordinary meat, and some diners, even for a plate of stir-fried vegetables, go thousands of miles to Bianliang to taste.

On the body of a big fat pig, the amount of plate oil is different, the less may only be a dozen catties, the more may have thirty or forty catties, and the one hundred and fifty catties of plate oil, Wang Song walked seven or eight slaughtering stalls, where are more than a dozen pigs made up, and the price spent is one level higher than ordinary meat.

When Wang Song bought it, he was a little strange, but he didn't ask much, plate oil is a condiment that is difficult to refuse for ordinary people, but for Zhao Xin, who is not tired of eating, it is not a big deal, it is not good to eat too much.

There are 120 people trained in Miaojiazhuang, and they will eat dozens of catties of meat every day, maybe a pig in four or five days, a pig that has been fed for two years, and the big fat pigs that are slaughtered, and the number of plate oil is also a lot, which is really a drop in the bucket for making soap.

What Zhao Xin wants is a soap that can sweep the entire low-end market, not just make it, just as a luxury accessory for high-end consumption.

Of course, animal fat is just a stepping stone, even if the whole Baozhou fat pig is killed, how much plate oil can be produced, and how much soap can be made, it is simply not able to supply the consumption of the entire Baozhou, let alone sell to other places through the convenient shipping in Baozhou.

On the one hand, vegetable oils and fats are cheaper, compared to animals that have to grow for a long time, animals whose yields cannot be controlled, plants are easier to control, and the yield is also larger, especially some oils that are not suitable for human consumption, for example, cotton oil, these prices are more than edible ones, I don't know how much immunity.

The cotton oil soap made of cotton oil has a stronger decontamination ability than ordinary soap, and there are not many chemicals, so it has become the first choice for baby clothes, and it is clean and does not irritate the skin.

In the future, Zhao Xin will definitely buy soybeans on a large scale, use soybeans to extract oil, and then support the entire soap industry.

At breakfast, Zhao Xin was still immersed in this process of thinking, in the modern society, he once made a handmade soap, his fellow sister, the female doctor in order to pursue the trend, tried to make handmade soap, and also asked him to discuss, for the production of handmade soap, or understand, he just considered the existing situation, and strive to be foolproof.

In fact, the difference between the Northern Song Dynasty and modern times lies in the manufacture of caustic soda, and because handmade soap will use strong alkali, it will be slightly dangerous. The most dangerous thing is not the process of making caustic soda, my sister's caustic soda is made of plant ash, to put it bluntly, it is a large number of impurities, among the plant ash, rich in sodium carbonate and potassium carbonate, strong alkali is a mixed solution of sodium bicarbonate and potassium bicarbonate, he now has a better choice, when he was in Nanle, when he lit up various cards on a large scale, he lit up natural soda ash.

I don't know which store this thing is lit up, the number of natural soda ash is not much, or in other words, the Northern Song Dynasty has not realized the use of soda ash, it may only be used as an auxiliary product of a certain kind, but it is cheaper Zhao Xin, the caustic soda made of plant ash, there are many impurities, which will affect the follow-up experimental process, using soda ash to make caustic soda is simpler and easier, and the purity of the caustic soda obtained is relatively high.

I was thinking, I don't know when, Green Lotus had already brought the meal to him, Zhao Xin looked at the exquisite meal, nodded, it was time to eat again, at the request of Wang Song, a few family members brought from the Miao family, there was still a unique ability to cook vegetables, his food has always been quite good, beckoning Green Lotus to eat together, Green Lotus practiced shaking his hand, and said that he wanted to eat with Ruyi.

When he was on the boat, Zhao Xin also had one or two meals with Luhe and others, but he didn't have one meal when he arrived at Miaojiazhuang, and he definitely couldn't finish the food at the moment, he didn't care about what the two maids ate, and it would definitely not be as delicate as him, so he was interested in it, and said jokingly: "Then let's go and see it together"

Lu He was very familiar with Zhao Xin, knew Zhao Xin's temper, led the way forward, and walked to the side hall.

In the small room of the side hall, Ruyi, and a few rough girls sent by Miaojiazhuang, are preparing to eat, in fact, the food is still good, four dishes and one soup, there is also a meat dish, it seems to be radish stew, it is impossible to do as fine as Zhao Xin, but it is quite enough, the meat pieces of inches and rounds, and the radish pieces of the same size, stewed together, fragrant.

Zhao Xin was very satisfied, he didn't treat his maid slowly, and was about to leave, but he saw a bunch of round, steaming things on it, he was stunned for a moment, pointed to this thing, and said with a little excitement: "This is a steamed bun"

Four dishes and one soup, eating rice porridge, for people in this era, these are a little insufficient, these can not become the staple food, so a plate of steamed buns, but Zhao Xin where there is no such thing, Zhao Xin is replaced by other things, such as some steamed products made of rice, steamed dumplings or shrimp dumplings, are made of rice as a material, and the production is quite fine.

A thought flashed through Zhao Xinxin, and he thought of a possibility, picked up the steamed bun, tore off a piece, and was about to put it in his mouth.

"Young master, don't eat" Ruyi said a little anxiously, their Zhuang family, even if the family background is not bad, the main daily meal is steamed bread, the noodles are cheap, and the steamed bread can also be made more, and it is full, but the only drawback is that the taste is not particularly good, very sour.

For those who can't eat, a little sour is nothing, in a famine year, even Guanyin soil, tree bark, and grass are eaten, it doesn't matter if it's sour, as long as you can fill your stomach.

Ruyi they are also accustomed to eating these things, for steamed buns, not many people like it, because of its taste, very sour and bitter, it is not a luxury to eat.

It's different for Zhao Xin, Zhao Xin is the young master, Wang Song has always said that he wants to give the best food to the young master, how can he give Zhao Xin such an unpalatable thing.

No matter how Ruyi is called, it is too late, because Zhao Xin has already eaten it, sure enough, a sour and astringent taste, and even a little bit of astringency and dryness, Zhao Xin knows, what is the reason for this, during fermentation, the yeast is not pure, part of it is normal fermentation, which makes the steamed bread more sweet, and the other part turns the flour into vinegar, which is not pure kind, it is some impurities, not particularly delicious.

The bitterness in the mouth, but the heart is becoming more and more open, this is also the stubborn disease of steamed bread, since the invention of steamed bread, there has been no solution to the stubborn disease, but later generations have solved it.

Later generations of steamed bread, fragrant and sweet, of course, is the use of good, pure yeast, the use of prickly head to make noodles, there will inevitably be impurities, in fact, even if there are impurities, the method of removal is quite simple, as long as a chemical is good.

This chemical is still the raw material for making caustic soda, and it is also the main use of this raw material in the folk
