Chapter 409: Ancient Soda Manufacturing

"Set the temperature and bake for about 18 minutes. You don't need to worry about the whole process, just wait for it to bake."

Li Yi set the time on the oven, turned around and asked with a smile, "How is it? Simple, right?"

"..."

Beside the camera, Huang Xiaoming and Wu Lei looked at each other, hesitantly muttering: "Simple... right?"

Although Li Yi made it, it did seem very simple, just kneading the dough and then dividing it into dough.

But they know that if they do it themselves, it may not be so easy.

"Practice makes perfect, and you will become proficient if you do it a few times."

Li Yi smiled and wiped his hands.

Wu Lei leaned forward, looked curiously at the dough nest inside through the transparent oven door, and couldn't help asking: "Brother Yi, don't you need to flatten this one? I think those peach cakes are all flat?"

"Need not."

Li Yi explained: "When I was kneading the dough, what was the baking soda I inserted with my finger just now? Isn't it for puffing it up?

When the temperature rises, the baking soda will naturally release carbon dioxide, forming a foam effect, and the peach cake will spread out. "

"So amazing?"

Wu Lei looked at the inside of the oven suspiciously.

"If you don't believe me, just take a look. The temperature will rise in a few minutes, and the flowers will bloom very quickly."

Li Yi said with a smile.

"Let me see."

Wu Lei was very curious, took out his mobile phone, and took pictures of the oven.

"I'll take a look too."

Zhao Jinmai pushed Liu Yifei, and also came to the oven, observing the peach cake inside.

And Master Cai also took a camera, set it in front of the oven, and took pictures of the inside.

This camera will take photos at a speed of 5 seconds for post-production time-lapse effects.

According to the speed of 5 seconds, 12 photos can be taken in one minute.

The minimum frame rate of dynamic images is 24 frames per second, so the photos taken every two minutes can form a 1-second video.

The oven is set for 18 minutes, so 216 photos will be taken, forming a total of 9 seconds of dynamic video.

From the audience's point of view, during these 18 minutes, the changes in the peach cake inside the oven will form a dynamic effect of just 9 seconds, as if time is speeding up.

This process, for the audience, only takes 9 seconds.

But from the perspective of Wu Lei and the others who were waiting outside the oven, the time was much longer.

However, after the first few minutes of heating time, the dough inside the oven began to change significantly.

The dough begins to rise slowly at a rate discernible to the naked eye.

The wide gaps between the dimples are quickly filled with dilated dimples.

During this process, the originally thick dimples, like melted butter, were spread into a ball, and gradually became the familiar appearance of everyone.

In the center of the dimple, the expansion of the dough is particularly obvious, as if it is slowly boiling, and the dough is even slightly puffed up by blowing.

However, as time passed, the bulge in the center of the dough slowly collapsed.

The superficial skin, which had just become thinner due to bulging, was cracked into gaps due to collapse.

Inside the gap, the foamy and crispy structure filled with pores leaked out, forming a color difference with the surface layer. It looked like a peach blossom was in full bloom.

This process happened slowly, but continuously and peacefully.

Wu Lei and the others were stunned for a moment.

They didn't realize until the oven bell rang that they had stuck their heads out and stared at the peach cakes in the oven for ten minutes.

"hiss!"

Wu Lei rubbed his waist and straightened up: "My waist!"

Zhao Jinmai supported Liu Yifei's wheelchair armrest. He was much stronger than him, but his neck was a little sore.

Rubbing his shoulders and neck, Zhao Jinmai sighed: "It's amazing! This side seems to be alive inside, I feel that it has been growing!"

Liu Yifei also nodded: "There is a feeling of life sprouting, which is quite decompressing."

"You are decompression, I am supercharger."

Wu Lei grinned and moved his waist: "My waist is almost broken."

Liu Yifei joked with a smile: "Where do children have waists?"

Wu Lei thought about it, and immediately put his hand down: "That's right! It must be an illusion."

"Tch! Don't push me away!"

Zhao Jinmai pursed his lips and complained, then turned to Li Yi and asked, "Brother Yi, you said that this peach cake was already made in the Ming Dynasty, but how could there be baking soda in the Ming Dynasty?"

"Eh? That's right!"

Wu Lei also clapped his hands, as if he had just realized: "There was no baking soda in ancient times? How did the peach cakes be made?"

Zhao Jinmai started fantasy mode: "Could it be that a modern female doctor of chemical engineering traveled back to the Ming Dynasty, invented soda, and made peach cakes?"

Wu Lei was not convinced: "Why not a male doctor of engineering?"

Zhao Jinmai looked at him and asked back: "Aren't boys always going to be emperors when they travel back in time? Who would want to make peach cakes?"

"Eh?"

Wu Lei thought for a while: "That's right!"

Seeing their nonsense in a serious manner, Huang Xiaoming laughed and complained: "You guys really treat it as a time-travel drama?"

Wu Lei spread his hands: "No one has traveled through time, how did the peach cakes be made?"

Huang Xiaoming didn't know how to answer, so he looked at Li Yi.

Li Yi smiled and explained: "Soda is soda ash, there was no soda ash in ancient times, but there was lye water!

The most common way is to burn dry rice straw into ashes and filter the water through gauze, which is natural alkaline water.

In the Guangdong and Guangxi regions, lychee trees and cinnamon bark are used to burn and filter with pine hair. The alkaline water obtained will also have a delicate fragrance.

The best thing to use is the ashes burned after drying the bean shells. Hakka people used to make lye rice dumplings with bean shell ash water. "

"Can it still be like this?"

Wu Lei was shocked: "How unhygienic is it to eat?"

"Who said it's unhygienic?"

Li Yi smiled and said: "Plant ash is the residue left by the fire, it is sterilized at high temperature, and it is very clean.

In ancient times, plant ash was a kind of medicinal material, and the ashes burned from plants and trees of different materials can also cure many diseases!

In addition to alkaline substances, the water filtered with plant ash also contains many trace elements and activated carbon, which is good for digestion. "

"so amazing!"

Zhao Jinmai was also amazed: "The ancients are so smart! Then we already knew chemistry a long time ago!"

"Of course."

Li Yi said with a smile: "In the Ming Dynasty's "Tiangong Kaiwu", many chemical processes are systematically recorded.

Engineering has always been inherited in the development of our civilization, but it's a pity..."

He didn't elaborate, just put on oven mitts and opened the oven door.

A crispy fragrance wafts out, not as fragrant as [Fresh Meat Mooncake], but it smells very comfortable.

Taking out the baking tray, Li Yi gently pushed it with a shovel, and the peach cake fell off, breaking up a layer of fine slag.

"Give me a taste."

Zhao Jinmai has already handed over the plate.

Li Yi scooped up one, put it on the plate, and tapped it lightly in the center with the spatula, and the peach crisp broke into several pieces.

"Isn't this too crispy?"

Zhao Jinmai couldn't help but marvel.

She took the chopsticks and wanted to try to use them to hold them, but found that she couldn't hold them at all.

Whenever she tried to use force, she would crush the edges of the peach cakes.

Finally, she pushed the peach cake to the plate with chopsticks, and picked it up sideways.

She couldn't wait to blow it, and she took a bite.

Sand~!

The crispy peach cakes have almost no hard texture, but the crispy ones fall apart when touched by the teeth.
