When Huang Xiaoming heard this, he 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 temperature of the oil in the pot is slowly rising, and the aroma of rapeseed oil is gradually beginning to diffuse.

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

Huang Xiaoming curiously glanced at the dark yellow rapeseed oil in the pot and asked curiously.

"Canola oil."

Li Yi said casually.

Liu Yifei smelled the aroma of rapeseed oil in the pot and was a little surprised: "Rapeseed is grown in many places in my hometown, and rapeseed oil is usually used for stir-frying, 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 from the Western Regions." ”

"Rapeseed oil is also produced in the Western Regions?" Liu Yifei was surprised.

"What is produced is not much."

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

The area and output of spring-sown rapeseed account for more than 90% of the total rapeseed in the country, and the planting areas are mainly distributed in the Yangtze River basin and the southwest region, that is, the area of your hometown Hubei Province, and the area of Yunnan, Guizhou, Sichuan and Chongqing.

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

Only Mongolian Province, Western Regions Province, Qingdao Province, Gansu Province and other northwest provinces have planted it, and some places in Northeast China also planted it, but it is not on a large scale.

The climate of the northwest provinces is relatively dry, so the water content of rapeseed is relatively low, the oil yield is high, and there are more flavor substances, and the taste will be a little more fragrant.

But it's also because the output is relatively small, so it's not easy to buy, I remember the last time I took you to the vegetable market grain and oil area to visit, I told the boss that I want to buy oil from the Western Regions Province? That's what I'm talking about. ”

Hearing Li Yi say this, Liu Yifei also remembered: "That's right! That time, you found several stores to buy oil from the Western Regions Province, and I thought it was some kind of oil! It turned out to be like this. ”

As he spoke, the aroma of rapeseed oil in the pot became more and more intense.

Li Yi stretched out his hand to feel the temperature of the oil, and then motioned to Liu Yifei: "Put your hand up and feel it, this temperature is the so-called fifty percent heat, and the oil temperature is about 140 °C." ”

Seeing this, Liu Yifei was a little afraid to stretch out her hand: "Touch it directly with your hands?" What if it crashes me? ”

"No, it will collapse if there is water in it, and it will collapse early."

Li Yi said with a smile.

Seeing him say this, Liu Yifei also plucked up her courage, and carefully stretched out her hand to feel it on top of the oil pot, but quickly shrank back.

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

"Mom! I'm most afraid of the oil pan! ”

"When I was a child, I was hit by an oil collapse once, and I had a big blister directly, and it took a month to get better, and now I still have scars!"

"The reason why I can't cook is because I'm afraid of oil crashing, it's too scary!"

"Collapsing oil is like a time bomb, you don't know when it will collapse, this feeling is the most terrifying!"

"I'd rather spend a little more money to eat out than make it myself."

Seeing Liu Yifei's nervous appearance, Li Yi was not reluctant, just turned off the fire and explained with a smile: "There is only one reason why the oil pot will collapse, and that is that there is water in the oil."

The oil temperature can easily rise above 100°C, but when the water reaches 100°C, it turns into water vapor.

The water in the oil pan turns into water vapor, and of course bubbles will form, which will float up and burst, and the oil will collapse everywhere.

So as long as you make sure to boil the pan dry and don't drip water into the hot oil, you don't have to worry about the oil breaking. ”

After speaking, he picked up the prepared spices, poured them into the oil pot, and explained while stirring: "The oil temperature of five or six percent is more suitable for soft frying, and the oil temperature is enough, which can stimulate the fragrance of the ingredients, but it is not too hot, and the ingredients are fried." ”

Liu Yifei looked at him without fear of hot oil, and was very envious, and then asked, "How do you judge how hot you say?" 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, but in the kitchen, we generally divide it into warm oil, hot oil, strong oil and strong oil.

Warm oil is three or four hot oil, about 90-130 °C, the oil pan at this temperature is very calm, and it does not smoke, but when you put your hand on the oil pan, there will be a slight feeling of heat.

Warm oil is suitable for stir-frying, making some more tender dishes, such as stir-fried shredded pork, stir-fried shrimp or something, this oil temperature is not easy to stick to the pan. ”

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

The oil surface will fluctuate slightly, turning around, and a small amount of oil smoke will come out, and 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 chopsticks into the oil pot, and sure enough, she found that the tip of the chopsticks began to bubble up.

"Really!"

Liu Yifei smiled and took back the chopsticks, and her fear of the oil pot was a little less.

Li Yi smiled: "Therefore, fear comes from the unknown, as long as we know it well enough, we will not be afraid of it." ”

"Hmm."

Liu Yifei nodded: "Next time I'll know how to use oil." ”

At this time, Huang Xiaoming on the side asked: "What about Wang oil and strong oil?" ”

Li Yi saw that the oil temperature was gradually cooling, so he restarted the fire, turned down the flame and explained: "Wang oil is seven or eight percent hot oil, and the oil temperature is 190-240 °C. ”

As he spoke, he pointed to the canola oil boiling in the pot and said, "Look, this hot oil is tumbling, right?" But if it's oil, it won't roll and will calm down again, but there will be obvious oil smoke, and there will be a sound of stirring with chopsticks. ”

"Really?"

Liu Yifei was a little curious when she heard this, holding her chopsticks, and seemed to want to try if it was true.

Seeing this, Li Yi reminded solemnly: "The high oil temperature of Wangyou is very terrifying, if it is splashed, it is likely to hurt the dermis and leave a permanent scar, so you must pay attention." ”

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

Seeing that she was obedient, Li Yicai nodded and continued: "The temperature of the strong oil can reach 250-300 °C, which is ninety to ten percent hot.

At this temperature, it is easy to catch fire in the pot, and the oil temperature reaches this temperature.

This oil temperature is only suitable for stir-frying, it is difficult to control without a professional chef, and it is best not to try it at home. ”

Speaking of this, Li Yi suddenly looked at the camera and reminded seriously: "Remember, if the pot is burning at home and there is a fire in the pot, don't water it."

Remember what I said before? Water vapor is also flammable, the oil temperature is too high, and when the water enters the pot, it will quickly transpire into water vapor, and then it will be ignited, and the fire will be bigger.

So, if there is a fire in the wok at home, just cover the pot with a lid, or cover the pot with something else to block its oxygen source, and the fire will naturally stop. ”

Hearing his reminder, the barrage in the live broadcast room swiped the screen.

"I've learned it, and I only know today what a hot oil pot is."

"Brother Yi is so good, he really teaches him by hand!"

"Don't take it seriously, there is a family in my community that caught fire because the pot was boiling, and water was poured into the pot, and as a result, the roof was set on fire, and the whole house was burned down."

"Last time, I watered the stir-fry on fire, but my eyebrows and eyelashes were burned, and my hair was burned, and I didn't dare to go out for half a month."

Liu Yifei looked at the tragic case of the audience in the live broadcast room and watched it bluntly.

"Forget it, I still don't try to cook by myself in the future."

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