Upon hearing this, Huang Xiaoming put down the stone mortar, wiped his hands and walked over, muttering: "Let me see what's going on?"

In front of the stove, the oil temperature in the pot is slowly rising, and the aroma of rapeseed oil is gradually beginning to spread.

"What kind of oil is this? It smells so good!"

Huang Xiaoming looked at the dark yellow rapeseed oil in the pot with curiousness and asked.

“Raise oil.”

Li Yi said casually.

Liu Yifei smelled the aroma of rapeseed oil in the pot and was a little surprised: "Raise is grown in many places in my hometown, and I usually use rapeseed oil for cooking, but this rapeseed oil seems to be more fragrant than the one I eat in my hometown."

Li Yi nodded: "That's right, this is rapeseed oil produced in the Western Regions."

"The Western Regions also produce rapeseed oil?" Liu Yifei was surprised.

"The production is just not large."

Li Yi explained: "If domestic rapeseed is divided according to the sowing season, it can be divided into autumn and winter rapeseed and spring rapeseed.

The area and yield of spring-soiled rapeseed accounts for more than 90% of the total rapeseed in the country. The planting areas are mainly distributed in the Yangtze River Basin and the southwest region, which is the area in your hometown of Hubei Province, and the area in Yunnan, Guizhou, Sichuan and Chongqing.

The planting area and yield of rapeseed sowing in autumn and winter is not large, accounting for less than 8% of the total rapeseed output in the country.

Only northwestern provinces such as Mongolian Province, Western Regions Province, Qing Dynasty Province, and Gansu Province are planted. In addition, it is also planted in some places in the northeast, but it is not in scale.

The climate in the northwest province is relatively dry, so rapeseed has a relatively low moisture content, high oil output, and more flavor substances, making the taste more fragrant.

But it is also because of the small output, so it is not easy to buy. I remember when I took you to the grain and oil area of ​​the vegetable market last time, I told my boss that I wanted to buy oil from the Western Regions? That's what I said."

When Liu Yi heard Li Yi say this, he also remembered: "Yes! You found several stores that time before you bought oil from the Western Regions Province. I thought what oil was talking about! It turned out to be this."

As I spoke, the aroma of rapeseed oil in the pot became stronger and stronger.

Li Yi reached out and felt the oil temperature, and then signaled to Liu Yifei: "Put your hand up and feel it. This temperature is the so-called 50% heat, and the oil temperature is about 140℃."

Seeing this, Liu Yifei was a little afraid to reach out: "Touch it with her hands directly? What if it breaks down?"

"No, it will collapse only if there is water inside. If it is broken, it will collapse sooner."

Li Yi said with a smile.

Seeing him say this, Liu Yifei also plucked up her courage and carefully reached out to put her hand on the oil pan and felt it, but she quickly shrank back.

Seeing this scene, the live broadcast room audience was also worried for Liu Yifei.

"Oh my god! I'm most afraid of oil pan!"

"When I was a child, I was crushed by oil once, and I had a big blister. It took only one month to get better. I still have scars now!"

"The reason why I can't cook is because I'm afraid of oil collapse. It's so scary!"

"The collapse of oil is like a time bomb. You don't know when it collapses. This feeling is the most terrifying!"

“I would rather spend more money to eat outside than make it myself.”

Seeing Liu Yifei's nervous look, Li Yi did not force himself, but turned off the fire and explained with a smile: "There is only one reason why the oil pan collapses, that is, there is water in the oil.

The oil temperature can easily rise above 100℃, but the water will turn into water vapor when it reaches 100℃.

The water in the oil pan turns into water vapor, and of course it will form bubbles, floating up and explode, and then causing the oil to collapse everywhere.

So just make sure to dry the pot and don’t drip water into the hot oil, so don’t worry about oil breaking.”

After saying that, he picked up the prepared spices and poured them into the oil pan. While stirring, he explained: "A oil temperature of 50% or 60% hot is more suitable for soft frying. The oil temperature is sufficient, which can stimulate the aroma of the ingredients, but it will not be too hot. Fry the ingredients."

Liu Yifei looked at him not afraid of hot oil at all, and was very envious, and then asked: "How do you judge how much hot you said? How do I know how hot it is?"

Li Yi explained while plucking the spices floating above the oil pan: "The oil temperature is about 25 degrees Celsius, but in the kitchen, we generally divide it into warm oil, hot oil, strong oil and strong oil.

Warm oil is 30% to 40% hot oil, about 90-130℃. The oil pan at this temperature is very calm and does not smoke. However, when you place your hands on the oil pan, you will feel slightly hot.

Warm oil is suitable for stir-frying. It is more tender to make dishes such as stir-fried shredded pork, fried shrimp, etc. The oil temperature is not easy to stick to the pan."

Speaking of this, Li Yi turned off the fire and pointed to the oil in the pot and explained: "Hot oil is this kind of oil, and the temperature is generally between 140-180℃.

Its oil surface will fluctuate gently, turning around, and a small amount of oil smoke will appear. If you insert chopsticks into it, there will be small bubbles around it."

Hearing Li Yi's words, Liu Yifei curiously took a chopstick and inserted the tip of the chopstick into the oil pan. Sure enough, she found that the tip of the chopsticks began to appear fine bubbles.

"Really!"

Liu Yifei smiled and took back the chopsticks, and she was less afraid of the oil pan.

Li Yi smiled and said, "So, fear comes from the unknown. As long as we understand it enough, we will not be afraid of it."

"Um."

Liu Yifei nodded: "Next time I will know how to use oil."

At this time, Huang Xiaoming, who was standing beside him, asked: "Where is the strong oil and the strong oil?"

Seeing that the oil temperature gradually cooled down, Li Yi turned on the fire again and adjusted the flames to explain: "The oil is 70% to 80% hot oil, and the oil temperature is 190-240℃."

As he said, he pointed to the tumbling rapeseed oil in the pot and said, "Look, this hot oil is tumbling, right? But if it is strong oil, it will not roll and will calm down again, but there will be a very obvious oil smoke. If you stir it with chopsticks, it will still make a simmering sound."

"Really?"

Liu Yifei was a little curious when she heard this. She held the chopsticks and seemed to want to try it out if it was true.

Seeing this, Li Yi reminded seriously: "The high oil temperature of Wang Oil is very scary. If it is splashed, it may damage the dermis and leave permanent scars, so be sure to pay attention."

Hearing his words and looking at his serious look, Liu Yifei also put away her curiosity and nodded seriously: "I know!"

Seeing that she was obedient, Li Yi nodded and continued: "The temperature of the oil can reach 250-300℃, which is 90% to 100% hot.

When it reaches this temperature, the pot will easily catch fire. When the cooking is cooked at home, the oil temperature reaches this temperature.

This oil temperature is only suitable for stir-frying. It is difficult to control it if you are not a professional chef. It is best not to try it at home."

Speaking of this, Li Yi suddenly looked at the camera and reminded him seriously: "Remember, if you cook at home and the pot is on fire, don't water it.

Remember what I said before? Water vapor is also combustible. The oil temperature is too high. When water enters the pot, it will quickly steam into water vapor, and then be ignited, and the fire will become even greater.

So, if the fire catches in the cooking pot at home, just cover the pot with a lid or cover the pot with something to block its oxygen source and the fire will naturally stop."

Hearing his reminder, the live broadcast room barrage flooded the screen.

"I learned it, but today I know what a hot oil pan is."

"Brother Yi is so nice, he is really a step-by-step teaching!"

"Don't take it seriously. There is a family in my community who caught fire because they were burning the pot and watering it. As a result, the roof was lit and the whole house was burned out."

"Last time I started cooking on fire, I watered it, but I burned my eyebrows and eyelashes and my hair was burned. I didn't dare to go out for half a month."

Liu Yifei was shocked when she looked at the tragic cases of the audience in the live broadcast room.

"Forget it, I'd better not try to cook by myself in the future."

She turned her head and looked at Li Yi, and said with a smile: "Brother Yi, if I have anything I want to eat in the future, I will come to you."
