Travel to ancient times and become rich women with your bestie

The two were about to agree, but then they remembered that their two original bodies were illiterate, so how could they understand what was written on the paper.

"Mr. Jiang, you are joking. We sisters are illiterate. Please read it to us after you finish writing it."

Mr. Jiang also realized that he had said something wrong, mainly because the conversation between the two just now gave him the illusion that they must be able to read. Mr. Jiang smiled apologetically at the two, picked up the brush, lowered his head and began to write a letter.

While Mr. Jiang was writing the letter, Zheng Yuan and Duan Minmin took out the things that Aji brought yesterday and took them to the kitchen, intending to try to make some toothpaste.

Theoretically, that formula is feasible, but in reality the most suitable proportion of each material has to be tried again and again.

Making toothpaste is not difficult. You just need to mix various materials together. The main problem is that the materials are not complete.

Aji brought them a bunch of cleaned clam shells and ground chalk. The two of them almost vomited when they took out the clam shells. They looked so clean, but they still smelled so bad. This stuff needs to be calcined. Let's use chalk today. When I have time, I will build a kiln and calcine it to see the effect.

There was no walnut oil either. Aji said he couldn't find anywhere that sold walnut oil, and he had never heard of anyone using walnuts to make oil before. So he had no choice but to buy a large bag of dried walnuts from the dried fruit shop.

This walnut looks of good quality, but it would be a pity to use it to extract oil. For large-scale production in the future, we will have to purchase wild iron walnuts from the mountains, which are cheap and have a high oil yield.

The equipment for distilling essential oils has not been developed yet, but this is not too urgent. I will go to Carpenter Li some other day to see if he can make a distiller.

Propolis is already available, and today all I need to make a basic toothpaste is walnut oil.

There are two ways to squeeze walnut oil, one is water substitution method, the other is pressing method. Pressing method requires a lot of strength, they have no equipment and no strength, today we will use water substitution method.

Their hands were almost broken after they finally peeled out the walnut kernels, filling two large basins.

The next step is to use the washed stone mortar to pound the walnut kernels, then put them into the pot and boil them over high heat. Soon a layer of walnut oil will float on the surface.

Scoop the walnut oil that keeps coming out of the surface into a colander to filter out the walnut residue until there is no more oil on the surface, which means that all the oil has been precipitated. Put the walnut residue aside to feed the pigs, and pour the filtered walnut oil into the cleaned pot for a second boil. When the water in the oil is completely evaporated, the walnut oil can be squeezed out.

In the end, we only got half a basin of walnut oil from two large basins of walnuts. It seems that the cost of this toothpaste is still a bit high.

The walnut oil just out of the pot is fragrant, but it is still a bit turbid. If you leave it for a few days, you will get clearer walnut oil. However, it has no effect on using it to make toothpaste.

After the walnut oil is made, the next step is to carry out saponification reaction to obtain glycerin. At this step, the two realized that without the calcination kiln, it would be impossible.

Although natural calcium carbonate can be used directly as an abrasive, a strong base is required for the saponification reaction. This step requires calcium oxide to react with water to form calcium hydroxide, which then reacts with the potassium carbonate in the wood ash water to form a strong base with a higher concentration of potassium hydroxide.

Seeing that the sun was setting, it was definitely too late to make another kiln. It seemed that the toothpaste could not be prepared today, so the two of them had to pack up the things in the kitchen and go out to see how Mr. Jiang's letter was.

Mr. Jiang put down the last stroke and lifted the paper to let the wind dry the ink on the paper.

Zheng Yuan and Duan Minmin walked over and glanced casually.

Hiss, they just said they would pretend to be illiterate, but now they don’t have to pretend anymore, it feels like they are illiterate.

I had the impression that traditional Chinese characters weren't that difficult to understand, but how come now they knew half of the characters, but they didn't know any.

Hmm~how come I’m not considered illiterate?

However, Mr. Jiang's handwriting is quite good, and it seems that he has practiced it a lot.

When Master Jiang saw them coming out, he gave them a rough outline of the contents of the letter. The two of them thought there was nothing wrong with it. Master Jiang was quite good at extracting key words, and he had already polished the core ideas and written them down.

Seeing that there was no problem with the two, Mr. Jiang asked Aji to bring the envelope over, put the letter tightly inside, and stamped it with Jiang's unique wax seal.

The two did not expect him to be so cautious, and they began to look at him with a new respect.

"Have you two aunts prepared the toothpaste?" After writing the letter, Mr. Jiang felt relaxed. He stood up and stretched and asked the two of them.

"Not yet. There is something that needs a kiln for calcination. We will hire someone to make it tomorrow and then match it."

The two of them talked about the current situation, and Mr. Jiang nodded without saying anything.

It was getting late, Zheng Yuan went into the kitchen to prepare dinner. Duan Minmin went over there and asked Taoer to come over to learn cooking, and of course the most important thing was to come over and help them light the fire.

Looking at the walnut oil on the side, Zheng Yuan thought of fried chicken and his mouth was watering.

Before, it was impossible to find oil for frying, but now that the oil has been found by the two of them, we can make fried chicken to satisfy our cravings.

It just so happened that among the ingredients that Mrs. Zhang gave me this morning, there were two big fat chickens, which were perfect for making fried chicken.

Zheng Yuan was always proactive when it came to cooking and he did what he said. Soon the two chickens were marinated and placed aside.

When Duan Minmin went over and called Taoer over, she saw two marinated chickens in the basin and her mouth was watering with greed.

After the rice was cooked and steamed, Zheng Yuan and Tao'er prepared two kinds of condiments, five-spice and spicy. Although not as good as those sold in later generations, they tasted very good.

The two still felt a little regretful. If there were tomatoes, they could make some ketchup; if there were potatoes, it would be even better, as they missed the taste of French fries very much.

Tao'er, however, held the two bowls of seasonings and couldn't let go. How could Aunt Zheng have such delicious recipes in her mind? She was amazed every time.

After the other dishes were scooped up, Zheng Yuan instructed Tao'er to pour in walnut oil. When the oil temperature was about right, she coated the marinated chicken with flour and put it in to fry.

A strong aroma of fried food diffused in the kitchen. Zheng Yuan and Duan Minmin sniffed the smell greedily. It was a modern smell.

After frying the chicken, looking at the remaining oil, the two thought about not wasting it, so they simply washed some eggplants, beans and corn, put them in and fried them all, sprinkled them with seasonings, and they smelled so good.

Day after day, the fragrance from their house never ceased. When the villagers smelled the strong aroma, they couldn't eat a single bite of their own food.

When the children came back and ate the fried chicken and fried vegetables, their eyes lit up. Other dishes were no longer attractive to them, and they all reached for the fried chicken and fried vegetables.

Young Master Jiang was also very surprised when he ate the fried chicken. He had been traveling around the country with the caravan for so many years and had never eaten it this way. This was definitely enough to open a restaurant. He looked at the two of them with a curious look.

The last two fried chickens were scraped clean, leaving only a pile of chicken bones on the table and the fried dishes were empty.

Zheng Yuan and Duan Minmin wiped their mouths and walked out of the kitchen with satisfaction. Life is so good!

After dinner, thinking about going to Yongding County tomorrow, they told Dashu and Erhe to remember to get up early tomorrow. They took the girls there to prepare tomorrow's ice jelly.
