Li Junxian looked at the recipe in his hand, which was very different from the recipes of this era. I saw that it was written braised fish, braised pork, braised pork ribs, braised chicken nuggets, stewed chicken, chicken soup, etc., as well as some fried vegetables. There are even some fried foods.

The villagers didn't know how to read, but in order to open a shop, Li Tong gave them some teaching, and they barely knew these menus.

And at this time, there is no stir-frying, not only because oil is very expensive. However, Jiang Wei asked the villagers to buy tea tree fruit for oil refining a few months ago, but he did not take it out for sale, as long as this thing enters the market, it will definitely be targeted. So at that time, Jiang Wei just let these villagers eat it themselves.

Jiang Wei, who has missed stir-frying for a long time, also passed on the stir-fry technique to the villagers, but the dishes he made himself were ordinary. After several months of hard work, the villagers' stir-fry technology has become very mature, and Jiang Wei has completely been compared. In the commercial street of Yunling Village, there are basically open restaurants. There are also some kebab shops. The main focus is food, which is also an idea of Jiang Wei, to make this a food street and a tourist attraction. Use your own characteristics to attract more people here.

Li Junxian was in a trance for a moment and asked the shopkeeper.

"Little Er, what are your signature dishes?"

The shopkeeper was recruited from the next village, and he also underwent some training before taking up his post. Xiao Er is a young man, he smiled slightly,

"Guest officer, our store can be said to be a signature dish. Mainly your taste, which one you prefer. ”

Li Junxian nodded,

"Let's have one of them."

Xiao Er smiled bitterly,

"Guest officer, there are only three of you, where can you finish eating? Our store advocates that saving is a virtue, no waste, no leftovers. Eat as much as you want. ”

Li Junxian was stunned, he didn't expect to come here for a meal, but he was preached by a junior second, and he was ashamed for a while. In the end, I ordered four dishes and one soup, three meats, braised pork, braised pork ribs, and a braised fish, a stir-fried vegetarian dish and an egg soup.

The standard of this table is very high, and this table of dishes costs nearly the same amount of money, and this price is quite expensive. Although the price is much lower than that of the big restaurants in Chang'an, it is very expensive compared to small restaurants.

Before the dishes came up, Xiao Er sent two plates.

"Three guest officers, this is a pre-dinner snack, appetizing, please try it first."

Li Junxian looked at it, hawthorn cake, and finally had a familiar one.

The first dish came up with braised fish, and before the dish arrived, a fragrance came to the nose, and I saw that the skin of the fish was dark and a little burnt.

Li Junxian's index finger moved.

"General, subordinates try it first?"

"No, this is not a place for nothing."

Li Junxian had already been attracted to the gluttony, picked up a piece of fish meat with chopsticks, and saw that under the dark burnt skin, the fish meat was white, tender and delicious. After eating it in one bite, Li Junxian's eyes couldn't help but light up.

The two subordinates saw that Li Junxian had almost eaten, so they began to move their chopsticks, and in a while, a fish was eaten and a fish head and fish bones were left.

Li Junxian began to look forward to it, this fish is so delicious, and the meat must be good.

Not long after, the braised pork came up, Li Junxian looked at the large piece of meat, the whole body was dark red, fat and thin, and he was very appetizing when he looked at it. Picking up a piece and eating it in his mouth, although it is not as exaggerated as the melt-in-your-mouth side, the delicious fat and the deliciousness of the meat are mixed together, all of which stimulate his taste buds at all times.

This dish is truly superb.

This is Li Junxian's first sense. But he really couldn't eat any kind of meat, so he couldn't help but be curious.

"What is this dish called? What kind of meat is it? ”

Xiao Er smiled politely.

"Guest officer, this is braised pork, it's pork meat."

"Pork?"

Li Junxian was surprised, in his impression, pork meat was not delicious. But this braised pork completely subverted his senses for pork meat.

Then I tasted the braised restaurant, fried vegetarian dishes, and tasted egg soup. After eating enough, Li Junxian thought about it, should this dish also be reported to His Majesty Li Er?

Li Junxian's arrival attracted anyone's attention, and after Jiang Wei gave Cheng Chuliang the task, he entered the laboratory, which was built in the most remote grove in the backyard of the villa, mainly researching some chemicals and some inventions that were not very dangerous, or relatively safe. It contains the chemical elements and some organic and inorganic materials that he made.

Jiang Wei came here this time mainly to continue to make materials about film. Among them, the film base and the developer have been made, and the rest is photosensitive materials, fixer, fixer and gelatin.

Of course, this film is certainly not comparable to the film of the previous life, and the wheel effect is definitely incomparable. After all, some sensitizers, stabilizers, anti-ash fogging agents, antioxidants, film hardening agents, and preservatives are missing.

But even without these, Jiang Wei was still able to make relatively rough films, and Jiang Wei had not touched the formulas of other things. Although it is much worse than these, the storage time is estimated to be relatively short.

And what Jiang Wei plans to make this time is fixer and stopper.

The anti-shadow liquid is simple, only 50 degrees of warm water, and acetic acid are blended.

The key is the fixer, which is more troublesome.

The materials are, water, sodium thiosulfate, sodium sulfite, acetic acid, potassium aluminum sulfate (alum).

Potassium aluminum sulfate is easy to obtain, and there is already alum in this era. Acetic acid is already produced when making TNT three-stage nitrification.

At present, what Jiang Wei does not have is sodium thiosulfate and sodium sulfite.

But it's not that these two things are unavailable.

First of all, sodium sulfite, the sodium carbonate (soda ash) solution is heated to 40 °C and saturated with sulfur dioxide, and then the same amount of sodium carbonate solution is added to crystallize without contact with air.

Sulfur dioxide, which can be produced by burning sulfur, the reaction equation: S+O₂=SO₂ (ignition).

After obtaining sodium sulfite, it is sodium thiosulfate, with the chemical formula Na2S2O3 and a molecular weight of 158.108. Sodium thiosulfate is colorless, transparent crystalline or crystalline fine particles. Comparatively speaking, the production is more complicated.

Jiang Wei used the sodium sulfite method to prepare sodium thiosulfate.

First of all, Jiang Wei planned to make sulfide alkali by using coal as a reducing agent to reduce miscanthus nitrate to produce sulfide alkali.

After obtaining the sulfide alkali, Jiang Wei began to start sodium thiosulfate. Firstly, the soda ash solution reacts with sulfur dioxide gas, caustic soda is added to neutralize, sulfide alkali is added to remove impurities, filtered, and then the sulfur powder is dissolved in the hot sodium sulfite solution for reaction, filtered, impurities removed, filtered, and caustic soda is added for alkali treatment, and the finished sodium thiosulfate is prepared by concentration, filtration, crystallization, centrifugal dehydration, and screening.

After Jiang Wei finished making the fixer, Liu Enyi brought a message at this time,

Chen Shuozhen is back.
