"When we choose fish, we first have to look at the fish eyes, fresh fish, full and convex, cornea transparent and clear," Li Yu opened the plastic bag, revealing the head of the fish, and said to the girl on the side: "Fresh fish, the eyeballs do not bulge, the cornea is wrinkled or there is blood in the eye." ”

"Really, this fish's eyes are red!" cried a sharp-eyed aunt next to her.

"Then, look at the gills of the fish, the gill filaments of the fresh fish are bright red, the mucus is transparent, the grass carp we bought is a freshwater fish, so there should be a fresh earthy smell," Li Yu lifted the gills of the fish again and handed it to the girl's voice: "What about this fish, the gills have darkened, gray-purple, and the mucus smells." ”

"Vomit-", the girl leaned closer and sniffed, her face instantly turned blue, and she ran to the side and retched.

At this time, the stall owner was already a little overwhelmed, cold sweat kept breaking out on his forehead, and Li Yu's words did not stop.

"Finally, we can touch the body of the fish, the surface of the fresh fish has transparent mucus, the scales are shiny and closely attached to the body of the fish," Li Yu turned over again, exposed the body of the fish, and said to an uncle on the side: "Stale fish, the surface of the mucus is more and opaque, the scales are glossy and easy to fall off, uncle, can you touch it?"

The uncle stretched out his hand and pulled it twice, and in the exclamation of the crowd, several fish scales fell off weakly.

When Li Yu was selecting fish, he found that 70% of the stall was dead fish, and some of the fish were even deformed, which was likely to be contaminated species.

The best result of eating this fish is diarrhea for a few days, and if one of the elements exceeds the standard, there is even a risk of food poisoning.

Li Yu threw the fish back in front of the stall owner, "This kind of fish, do you dare to say that it is fresh? Do you want me to find a pot, let's kill it and cook it?"

"There's no need to kill and cook," the crowd parted from the outside in, and several men in police uniforms walked in, led by a man with a Chinese face wearing gloves, who bent down to put the dead fish in a plastic bag.

After the man stood up, he said to the pale stall owner: "We are from the food safety center, and we received a report in the morning, someone bought a 'live fish' from you the day before yesterday, and the diarrhea did not stop after eating, and now the residual sample has been taken for testing, please go with us to assist in the investigation." ”

After the man finished speaking, he walked behind his back, and two people stepped forward to control the stall owner, and the other people began to clean up the stall, these fish are all physical evidence.

The man with a Chinese character face took off his gloves, walked in front of Li Yu, and gave a thumbs up: "We saw the whole process on the side, the little brother is young, and his knowledge reserve is so rich, amazing!"

Li Yu smiled and said a few polite words to the man with the national character face, and after a few minutes the stall was cleaned up, the national character face and Li Yu said goodbye and closed the team.

Looking at the fishmonger who was taken away by the police, Li Yu shook his head, this kind of contaminated fish, the purchase price is only a quarter of that of ordinary fish, and in the face of nearly three times the profit, there are always people who will abandon the bottom line.

The fishmonger was taken away, and Li Yu, who was in the limelight, was surrounded by a group of uncles and aunts, and in desperation, he had to say several common material selection techniques and found an opportunity to sneak out.

Yiyi is very excited, the child is already happy, jumping around and spinning, in the words of the previous life, it is Li Yu who killed the super god on the field, and the little girl shouted 666 on the side and won by lying down.

............

Next, Li Yu took the little girl around for another half a circle, and finally found another fish stall.

"Eh, is it you?" Li Yu was about to pick a fish, someone patted him on the shoulder from behind, Li Yu turned his head, and found that it was the girl just now.

"Thank you just now," the girl stuck out her tongue embarrassedly, gestured with her fingers a few times, and said, "I wanted to thank you for coming, but it turned out that a group of aunts surrounded you ......"

"It's okay, it's just a gesture, I just can't see it. Li Yu hurriedly waved his hand, he didn't say anything nonsense, if someone else wanted to buy fish just now, he would have reminded him.

The girl looked like she had palpitations, after all, if she really bought dead fish, she was lucky to have diarrhea and diarrhea, and she was lucky enough to go to the hospital for rescue.

"By the way, I forgot to introduce myself," the girl patted her head and stretched out her hand towards Li Yu: "My name is Huang Yuwei, what about you?"

"My name is Li Yu, this is my sister Yiyi," Li Yu stretched out his hand and shook Huang Yuwei gently, and the little girl also said hello with a smile, he pointed to Huang Yuwei's vegetable basket and said, "Have you chosen your fish?"

Huang Yuwei's expression suddenly became bitter: "Not yet, what happened just now, I hesitated here for a long time, and I didn't dare to buy it." ”

Li Yu blinked his eyes and said, "You buy fish...... What are you going to do?"

Hearing Li Yu's question, Huang Yuwei's white face turned a little red, and said, "I, I don't know, add some sugar or something, and cook it." ”

Li Yu looked at the sky speechlessly, why don't you add some sugar and cook it, this is a rookie.

"That's it," Li Yu shook his head, pointed to a water tank, and said, "I suggest you buy osmanthus fish, well, that's the kind of thing, but the price will be more expensive." ”

Huang Yuwei followed Li Yu's finger and saw that in another glass box, there were several live fish swimming with obvious bulges on their backs.

"The price doesn't matter," Huang Yuwei looked at Li Yu, he knew that Li Yu would definitely teach her how to do this, "Is this fish easy to make?"

"This kind of fish is called mandarin fish, but everyone is used to calling it osmanthus fish, it is easier to make than grass carp, you eat it from your own family, right?" Seeing Huang Yuwei nodding, Li Yu continued: "You buy the osmanthus fish, slaughter it from the abdomen, and don't chop off the fish head......"

"Please wait a minute," Huang Yuwei interrupted Li Yu's words, took out her mobile phone from her bag, clicked into a chat interface, and pressed the voice button, "You continue." ”

"......." Li Yu silently rolled his eyes in his heart, and continued, "After slaughtering, add some salt and marinate for a while, if you don't grasp it well, you can marinate it a little lighter, and add some seasoning after the finished product, and then you swing the fish horizontally, cut three or four knives vertically on the fish body, one or two centimeters apart from each knife, then add some cooking wine, stuff some ginger slices in the abdomen after finishing, pour some steamed fish soy sauce and steam for ten minutes, then pour out the soup and pour hot scallion oil." ”

After speaking, Li Yu's hand pointed in one direction and said, "I just saw a non-staple food store over there, cooking wine and steamed fish soy sauce should be sold in it, if there is no soy sauce, it can be replaced with soy sauce, and the raw material is black beans." ”

Li Yu taught Huang Yuwei that it is very suitable for novices to fish with scallion oil, the operation of scallion fish is simple, the production of most of the fish, the heat is a big difficulty, and the steamed fish can be as long as it is stuck in time, which is undoubtedly much more friendly for novices.

The most important thing is the freshness of the fish, there are not many types of fish on this stall, so Li Yu recommended the most suitable osmanthus fish, this kind of fish is full of meat, the taste can be said to be MAX level, and it is a very suitable ingredient without price pressure.

When the kitchen novice is full of ingredients, the most difficult point in making scallion oil fish is pickling, and if you are not careful, you may die of saltiness, so he specially reminded Huang Yuwei that you can marinate it lightly when marinating, anyway, it is a family banquet dish, and after serving it, I feel that the taste is not enough, and it is harmless to add some condiments.
