A mouthful of fried rice at a sky-high price, Old Tang apprenticed on the spot

Chapter 403 Aluminum-Free Baking Powder

After handing over the dried fruit to Zhao Jinmai, Li Yi brought over two catties of low-gluten flour.

Afterwards, he cleaned and scrubbed the stainless steel table next to it, took the lard bowl, scooped out about a catty of lard from it, and poured it on the table.

For white chefs, the chopping board is the most important thing in making pasta.

In ancient times, the chopping board for cutting meat was called zu, that is to say, the man made the knife zu, and I made the fish zu.

There is a record in "Shuowen Jiezi": Zu, Li Zu also, from the half of the meat on top, side Lu Qie.

At that time, Zu was a ritual vessel used for cutting meat. It looked like a small bench and was mainly used for cutting meat.

The table refers to the table for processing grain. Although it looks similar to Zu, it is equipped with a grinding rod to grind the outer shell of grain.

"Shuowen Jiezi Volume [-]" wrote: "Case: Hehe also, from the sound of He'an, grind the ear of the grain to get the grain."

The so-called 轹 is also recorded in "Shuowen Jiezi Volume [-]": "轹: Che Suo Jian also."

Later, Zu evolved into Caidun, and case became chopping board.

The white case chef has high requirements for the chopping board, and will not let others mess with it easily.

Every white chef has his own special chopping board, and it must be made of pear wood.

There is an old saying that "the willow wood vegetable pier pear wood table, the mulberry pole does not grind the shoulders", which means that the chopping board made of pear wood is the best.

The wood of pear wood is delicate, hard in texture, wear-resistant, rot-resistant, insect-resistant, durable, and has a light fragrance.

Moreover, pear wood is more water-resistant and not sticky.

When white chefs make pasta, a lot of flour and oil will fall on the chopping board. If it is a pear wood chopping board, it will be more convenient and simple to handle.

In ancient times, it was not cheap to get a pear wood table.

But in modern times, stainless steel kitchen worktops can be found anywhere, and they are extremely smooth, much easier to use than pear wood chopping boards.

The method of making peach cake is very simple, and the raw materials are also very common, mainly flour, eggs, oil and sugar.

The ratio of flour, oil and sugar is about 2:1:1.

The ratio of eggs to flour is 1:10, that is, one catty of flour with one or two eggs.

Unlike making [Fresh Meat Mooncakes], Li Yi first mixed lard and sugar, and beat them into a sugar paste by hand.

Then, he took 10 grams of baking powder, put it into the flour, stirred it evenly, and then poured it on the sugar and oil paste.

Seeing the name marked on the bag of baking powder that Li Yi took out, Huang Xiaoming couldn't help asking: "This kind of baking powder doesn't seem to be edible, right?"

In the live broadcast room, after the audience saw the name of the baking powder, they also posted barrages and raised doubts.

"Brother Yi, why do you use baking powder? Isn't this stuff unhealthy?"

"Didn't it say that eating too much baking powder is easy to cause Alzheimer's disease?"

"This thing is not fun to eat!"

"Brother Yi, brother Yi! I didn't expect you, a guy with thick eyebrows and big eyes, to betray you! You are using technology and hard work!"

Seeing the audience's doubts and complaints, Li Yi explained with a smile: "I use aluminum-free baking powder here, which is very safe.

The kind of baking powder that contains aluminum is harmful to the body. "

"Is there a difference?"

Huang Xiaoming asked in puzzlement.

"Of course there is a difference."

While mixing the flour with a scraper, Li Yi explained: "Baking powder is actually a kind of alkaline soda powder, mixed with acidic substances, and filled with starch.

It mainly uses acid-base reaction to release carbon dioxide and form air bubbles in the food to achieve a fluffy effect.

The previous technology is in place, and in order to save costs, some manufacturers will use alum-like substances as acidic substances to make baking powder.

Alum contains aluminum, which will indeed cause damage to the human body.

In the past, some fried dough sticks shops used this aluminum-containing baking powder as an additive to make the fried dough sticks more fluffy.

It was later reported by the media, and after it spread, it became a rumor that eating fried dough sticks would make you stupid. "

"That's right, that's right."

Zhao Jinmai nodded again and again: "My mother often tells me to tell me not to eat deep-fried dough sticks when I eat out, or I will become stupid."

Huang Xiaoming also laughed and said: "I also heard people say that fried dough sticks are made with washing powder. It should be a rumor."

"Of course, with washing powder and noodles, a fool can eat them. How is that possible?"

Li Yi smiled and said, "That's a rumor spread by people who don't understand baking powder."

Wu Lei was listening, and asked curiously, "Then won't this baking powder make you stupid?"

"It's aluminum-free baking powder and it's still pretty safe."

Li Yi explained: "The baking powder containing aluminum, mainly alum, is not safe.

Now this aluminum-free baking powder has replaced acidic substances with citric acid, glucono-δ-lactone, and some phosphates, such as disodium dihydrogen pyrophosphate, calcium dihydrogen phosphate, and sodium dihydrogen phosphate etc.

These sour agents are all harmless to the human body, and contain nutrients such as phosphorus and calcium, which are beneficial to human health. "

"what?"

Zhao Jinmai asked in surprise: "According to what you said, is this baking powder good for the human body?"

"There are certain benefits, but you can't eat too much!"

Li Yi smiled and said: "Baking powder will release carbon dioxide when it dissolves in water. If you eat too much, it will release gas in your stomach. Naturally, your body will also automatically exhaust gas, so..."

He didn't continue to explain, but everyone understood what he meant.

"Hiccup~!"

Wu Lei hiccupped.

"Alas!"

Zhao Jinmai fanned the wind in disgust.

"Hey what? It's called Qingqi rising."

Wu Lei glanced at her, then suddenly put his hands down, and growled in a low voice: "The turbidity is falling!"

"what!"

Zhao Jinmai screamed and hid behind Liu Yifei, pulled her back, and shouted: "Wu Lei! If you dare to fart, you will die!"

"Humph!"

Wu Lei smiled triumphantly and curled his lips: "Scared you to death."

Seeing their quarrel, Li Yi shook his head helplessly, then wrapped the reconciled dough with plastic wrap, put it aside and woke up.

The dough for peach cakes has been reconciled here, and the watery noodles of the [Fresh Meat Mooncake] have also been awakened.

Li Yi took out the water and oil noodles, and the dough had become sticky again.

Li Yi was not surprised, he kneaded the water and oil surface again to make its surface smooth, then wrapped it in plastic wrap again, and woke up for another 10 minutes.

After 10 minutes, the water oil surface has completely woken up.

Li Yi took it out, flattened one side, and gently pulled it with his hands, the water and oil surface stretched out, like rubber, very light and thin.

"That's enough."

Li Yi showed it to the camera, and kneaded it together again.

Then, he took the dry pastry and kneaded it again, so that the whole ball of dry pastry was kneaded thoroughly.

Afterwards, he put the dry pastry and water oil noodles together, and said to the camera: "Next, we are going to open the pastry."
