«——【· Preface ·】——»
In 2011, a reporter in Chongqing secretly visited a fishmonger in a local vegetable market, only to see that the fishmonger added something to the water, and immediately brought the fish back to life in the dead silence in the water!
After the reporter's exploration, it was learned that this kind of "zombie powder" that can increase the excitement of sick fish is called fish floating spirit in the industry.
In fact, it is the so-called solid hydrogen peroxide, and once it is thrown into the water, the gas produced will bring back the light to the fish that are dying due to lack of oxygen.
This will briefly help the fish to live longer.
Some customers saw the fish jumping around in the fish tank, thinking that the fish was very fresh, so they asked the vendor to process it and buy it and eat it at home.
Later, after expert research, the substances contained in this fish floating spirit are easy to cause cancer!
Hearing this, do you dare to take the live fish home directly? So before buying fish, you still have to discern carefully.
Although the state banned the use of fish floating spirit as early as 11 years after it was exposed, for its own safety, you still have to judge whether the fish is new or not fresh before buying it.
«——【· to distinguish whether the fish is fresh ·】——»
Here, I would like to share with you a few tips for judgment.
The first point to see if the fish is new or not is to look at the fish eyes.
People who often buy fish or know how to do it will look at the eyes of the fish as soon as they get it.
The color of the fish's eyes is the best proof that the fish is not fresh.
The darker the eyeballs, the shorter the time it takes for the fish to be caught and stored in the warehouse.
If you go fishing a lot, you will occasionally see the carcasses of fish floating on the surface of the water.
The long-dead fish has white eyes and sunken eyeballs.
You can smell the smell of rotting from afar, and there are many unscrupulous merchants who will buy dead fish at a low price and put it in the freezer for preservation.
There is no difference between live and dead fish on the surface after they have been frozen.
In fact, the color of the eyeballs can roughly determine the time of death of the fish.
If it is a fresh fish, the contours of the eyes will be very full, and the cornea will be transparent, which proves the freshness.
If there is a blood spot around the fish's eyes, look at the shade of color, if the blood is light, it means that the fish has just been caught.
If the blood is severe and dark red, it means that it has been caught for a long time.
«——【· Look at the Fish Tongue ·】——»
In addition to the eyes of the fish, you can also tell if the fish is fresh by looking at the tongue.
Freshly caught fish have a brightly colored tongue and are tough to the touch.
This is a proof that the fish has a relatively strong vitality, of course, while opening the fish's mouth, you must also be careful of the barbs in the fish's mouth.
Some fish have very sharp barbs in their mouths, and if they are accidentally punctured, the exposed wounds are susceptible to bacterial infection.
Most fish mouths contain bacteria, and if they are punctured, they should be disinfected as soon as possible.
Back to the topic of fish tongue.
If you open the mouth of the fish and find that the tongue of the fish is shallow, and the tongue is soft to the touch, it means that the fish has been caught and landed for a long time.
At this time, you have to think carefully about whether to buy this fish or not.
«——[· Look at the gills ·]——»
The gills are also an important indicator of whether the fish is alive or not.
However, before opening the gills, be concerned about the barbs growing under the gills.
Like fish mouths, these barbs can easily puncture a person's skin, causing wounds to develop.
Moreover, some fingerlings have very dense barbs under the gills, so it is best to pry them open with clips or other things.
Once the gill shell is opened, take a closer look at the color of the gills.
If the color of the gills is dark red or purplish-red, then the fish should not be bought anyway.
Conversely, if the gills are bright red and bright, the fish is very fresh.
You can even get close to the gills of the fish and smell it, if you smell a fishy smell, it means that the fish has been caught for too long.
On the contrary, if you just smell a simple fishy smell and do not stink, it proves that it is really fresh.
The gills are the filter of the fish, and there are often some dirt left in it, and the freshness of the gills also determines whether the fish is fresh or not.
The better the filtration of the gills, the more food the fish ingests, the more tenacious it is.
But when cooking, don't forget to remove the gills.
Although gills are important to fish, almost all of the dirtiest things on a fish's body are hidden in the gills.
Studies have shown that fish gills harbor a large number of bacteria and parasites.
«——【· Touching the Fish Body ·】——»
The last move, and the easiest, is to start with the fish.
The first three moves all start with the fish head.
But some bosses are very cunning and will cut off the head of the fish first when selling it to you.
At this time, you can only judge whether the fish is alive before slaughter by the body of the fish.
It's simple, you just have to press the fish.
The texture of the fish is soft, but it is very tough.
Normally, when you press the body of a freshly caught or freshly killed fish, the flesh of the fish will immediately bounce back.
And there is a layer of fresh mucus on top of the scales.
This means that the fish are slaughtered freshly caught.
Using these four points, it is enough to pick fresh fish in the market.
«——[How to deal with fish · in ·]——»
So after bringing the fish home, how to deal with it has become a problem.
Although we can also ask the stall owner to help with it, sometimes it is difficult to avoid taking it home to deal with it.
For example, during the New Year's holidays, relatives bring two big fish to the door.
Or when cooking during the Chinese New Year, you can't hold a fish by yourself and find someone else to deal with it, right?
The reason why many people don't want to make fish is because it's a hassle to handle.
The biggest headache is the fish scales.
The first step in dealing with fish is the dense scales.
If it's a big fish like a carp, it's fine, and you can clean it with a few scrapes with a kitchen knife.
But if it is a small fish species like yellow croaker, the scales are soft and thin, and if you want to deal with it, you have to scrape it several times, which makes it miserable.
In fact, it is very simple to clean up the fish scales by simply changing your thinking.
Find a piece of hard fruit or vegetable, preferably lemon, so that you can remove the scales and smell at the same time.
Cut off the top piece and start scraping along the top, starting at the tail of the fish.
You can shave the scales off little by little very smoothly.
It's much faster and easier than using a knife.
If you don't have lemons at home, both apples and ginger can do the same.
After descaling, the fish has a second layer of protection, which is the mucus it carries.
Usually, this layer of mucus has to be washed several times before it is washed off.
Otherwise, if you cook with it, the fishy smell will never get rid of it.
But we have a way to deal with it.
That is, the fish body is cleaned after soaking in cornstarch in water.
The starch will absorb the mucus from the fish, and if you touch it again, you will find that the fish is very dry and not as smooth as mucus.
This means that the mucus has been almost processed.
If you don't have cornstarch at home, you can actually change it to other starches, or even use flour directly.
After the fish is cleaned, whether it is steamed or fried, it can be made with both color and flavor.
Keep these tips in mind and you'll never have to worry about handling fish again.
