Why does my stewed fish smell earthy?

The breadth and profundity of Chinese food culture is reflected in all aspects of daily life. People can use the same ingredients to make a variety of delicious dishes, just like a fish, which can be steamed, braised, fried, chopped peppers, boiled, stir-fried, shabu-shabu, and so on. <>

In fact, if the fish is cooked well, it will taste delicious. But if you don't do it well, it tastes particularly fishy, because it grows in water. Therefore, it is fresher than other ingredients, but if it is fishy, there may be one of the following reasons. <>

First of all, in the processing step of the fish, the fishing line is not removed, this thing is located in the body of the fish, about 2cm below the head of the fish, a shallow knife, and then a knife above the tail of the fish, you can see a white line, just pull it out, otherwise the fish will have a fishy smell. <>

Secondly, when making fish, it is indispensable to use peppercorns and ginger slices, both of which have a great effect on removing the fish, and you can also add a little cooking wine if you have the conditions.

Perform deodorization. If you have both of these steps, but the fish still smells fishy, it may be that the fish is bruised in the belly of the fish when handling the fish.

Not clean, like this case, next time you have to rinse the gills several times.

and all the blood in the stomach can be removed.

In fact, there are two ways to ensure the deliciousness of the fish to the greatest extent: steaming and stewing. Like sea bass, which has delicious meat and relatively few spines, you can clean it and put it on a plate, add a little ginger slices and shredded green onions to remove the smell, put it directly in the pot and steam it, and put a little steamed fish soy sauce after it comes out of the pot.

It's a delicious dish.

The second is the stew, which is also fish soup tofu. Fish soup and tofu have always been a perfect pairing.

exists. First of all, put the fish in a frying pan and fry it on both sides until it is slightly yellow, then pour in hot water, add tofu, and simmer for half an hour. You'll get a milky white fish broth. In addition to adding a little ginger and shredded green onions, add a little salt to taste before removing from the pan.

In fact, there is a line in the body of the fish, called the fishy line, if you don't remove it, no matter how you do it, it will be very fishy, and the stewed fish always feels an earthy smell. It turns out that the fishy line is used to concentrate impurities in the body, and you can also feel the light and temperature in the water and the quality of the water, which is a more sensitive part of the fish. The earthy smell in the water will adhere directly to the fishy line, and it can be removed when eating to reduce the fishy smell.

Grass carp, crucian carp and carp have more pronounced fishy lines and are easy to remove, while marine fish do not have as distinct fishy lines as freshwater fish. This line is in **? How to remove?

The location of this fishy line is very easy to find, just below the gills. Place the fish flat on the board and make a cut under the gills and then on the tail of the fish, not to cut deeply, but to half the thickness of the flesh. Then use the side of the kitchen knife to pat the fish a few times, and you will notice a white spot on the flesh of the knife.

Gently pinch and pull outward, and a thread like a hair will be pulled, and this thread is called a fishy thread. Turn over the body of the fish and pull out the thread on the other side, so that the fishy smell can be completely removed.

It is possible that the fish is not cleaned, because the fish is more difficult to clean, so be sure to clean it carefully. In addition, after the fish is washed, you can rub the fish with salt to remove the fish, and you can add some cooking wine when cooking fish to remove the fish.

Because you don't get rid of the fishy smell in the fish, the taste will be very poor, so you must use wine to remove the fishy smell first, so as to avoid this situation.

Grab the fishy line from the back of the head with one hand, gently pat the body of the fish with the knife with one hand and slowly pull out the line, and the other side is the same. The fishy line is more fishy, and it can reduce the earthy smell after being removed. Change the knife and cut it into the shape you need, put it in a container and rinse it for 10 minutes to completely remove the residual blood.

If the black membrane is not cleaned, some fish and teeth, such as grass carp, must be cleaned. After washing, rub the top with salt, and then wash off the salt to remove the fishy smell. When cooking fish, add cooking wine, vinegar, ginger, and pepper to remove the fishy smell.

Some authoritative biological experts have studied that some cyanobacteria and green algae can produce substances with earthy odors. It is also believed that certain species of the phylum Diatoms and actinomycetes can also produce an earthy odor. The earthy smell enters the bloodstream through the gills, so it has an earthy smell.

The first method is to wash the fish and put it in cold water, then pour a small amount of vinegar and pepper into the water, or put some bay leaves. After such treatment, the fish does not have an earthy smell.

Why does the fish sometimes have an earthy smell, it may be when the fish is cooked, the seasoning is not adjusted well, when the fish is cooked, put some coriander root or celery and the like, and the green onion, ginger and chili pepper can not be less, put garlic cloves out of the pot, and the next time you cook the fish, put beer to try this is also good.

But there is a layer of transparent mucus on the surface of some fish, if it can not be removed, there will be a heavier fishy smell, add a small spoon of salt to the bowl, and then add an appropriate amount of flour and stir well, rinse the surface of the fish with clean water first, and evenly spread the evenly mixed flour on the fish, this is because the living environment of freshwater fish, such as fish ponds and lakes, has more humus, which is very suitable for the growth of microorganisms. Studies have shown that some cyanobacteria and green algae organisms can produce substances with an earthy odor. It is also believed that certain species of the phylum Diatoms and actinomycetes can also produce an earthy odor.

It's because the fish wasn't washed when they were cleaned. When cleaning up, the fish should be washed before cooking, otherwise it will have an earthy smell when eating.

It's that we didn't do it the right way. The body of the fish should be cleaned, and then ginger, garlic, and various spices should be added to marinate it to remove the fishy smell.

It may be that the fish has not been cleaned up, if there is a taste, you can add some cooking wine or use green onions. Ginger and garlic are spread on the fish, so that the flavor can be removed.

Some fish will have an earthy smell because many fish are artificially farmed, especially freshwater fish, which has a particularly fishy smell, and this kind of fish is difficult to eat.

Because freshwater fish generally have some earthy smell, which has a certain relationship with the living environment and food of freshwater fish, but under normal conditions, the fish does not have any earthy smell after cooking.

Because it is closely related to the environment in which the fish grow. Some fish live in places where the soil is more fertile. If this continues, no matter how much pickling you try, there will still be a certain earthy smell.

This is because the process of removing the smell is not very good, and attention should be paid to treating it with green onion and ginger cooking wine.

Some fish will have an earthy smell when made, what is the reason for this?

Hello dear! We'd be happy to answer for you! This is because you didn't handle the fish cleanly!

Fish have an earthy smell, which is related to the environment in which they are grown. In the process of aquaculture, the nutrients in the water are easy to be excessive, resulting in eutrophication of the water body, which becomes an excellent medium for microorganisms. The "flavor substances" produced by their metabolism are also released into the water body in large quantities, causing the concentration of earthy odor substances to increase exponentially.

In such a high concentration of water, various freshwater fish are quickly "pickled into taste" through the absorption of gills, ** and digestive tract. Fishy substances are highly lipophilic and easily absorbed by the body surface, and can penetrate from the water body into the fish body in a few minutes, while it takes days or even weeks to excrete them. This makes it easy for earthy substances to accumulate in the fish – the bigger the fish, the more "intense" the flavor.

How to remove the fishy smell: 1. After washing the belly of the river fish, put it in cold water, and then pour a small amount of vinegar and pepper into the water, or put some bay leaves. 2. You can use half a tael of salt and 5 catties of water to soak the live fish in the salt water, and the salt water will be soaked into the blood through the two gills, and after one hour, the earthy smell will disappear.

If it is a dead fish, soak it in salt water for two hours. 3. The white tendons on both sides of the carp's back are the source of creating a special fishy smell. 4. When slaughtering fish, the blood of the fish can be rinsed as much as possible, and the cooking is to add onions, ginger and garlic to taste.

Dear, <>

The above is the answer I summarized for you, I am very happy to serve you, please give me a thumbs up, thank you very much for your <>

I hope mine is helpful to you, and then I hope you are happy every day, have a good life<> and good luck always accompany you<>

The biggest impact is the growing environment. The organic matter content in the water body is too high, and the fish will have a muddy smell, especially the thick bottom mud, and the fish produced in the stagnant ponds accumulated over the years of sedimentation cannot be eaten at all. A smell of mud or diesel....After this kind of fish is caught, it is put in a clean flowing water source for a certain period of time, and there is no peculiar smell.

But it's not very safe to eat.

Because it has to do with the environment in which it grows.

Chen Shunsheng, professor and director of the Department of Aquatic Product Processing and Storage Engineering at the School of Food Science and Technology of Shanghai Ocean University, said that freshwater fish such as carp, grass carp and silver carp generally have an earthy smell, which is closely related to their growth environment.

Freshwater fish generally grow in ponds, rivers, and lakes, where there is more humus and are suitable for microbial reproduction. Bacteria with an earthy smell attach to plankton such as diatoms and cyanobacteria, as well as some aquatic plants, and freshwater fish ingest these substances through the food chain, which then enter muscles, blood, and tissue cells;

However, there is obviously less humus and plankton in large water bodies such as large rivers, large rivers, and reservoirs, and the earthy smell of fish living in them is also relatively weak.

Freshwater fish are washed and dissected.

After belly, put it in refrigerated water, and put a small amount in the water.

After soaking the vinegar and pepper of bai, the earthy smell will be significantly reduced or eliminated. You can also dissolve 200 grams of table salt in 2,500 grams of water, put live river fish in salt water, and soak for one hour to disappear the earthy smell.

Fish that can live in freshwater with a salinity of 3 parts per 1,000 are called freshwater fish. In a narrower sense, it refers to fish that have only a juvenile or adult stage in their life cycle, or that they must spend their entire life in freshwater. There are about 26,000 species of known fish in the world, and about 8,600 species of freshwater fish.

There are nearly 3,000 species of fish in China, including more than 1,000 species of freshwater fish. There are about 26,000 species of fish known in the world, which is the largest group of vertebrates, accounting for about the total number of vertebrates. The vast majority of them live in the ocean, and there are about 8,600 species of freshwater fish.

There are nearly 3,000 species of fish in China, including more than 800 species of freshwater fish.

Nutritive value. Bighead carp has the effect of warming the stomach and nourishing blood, dispelling head wind, and benefiting the brain and marrow, and has a certain effect on dizziness and dizziness caused by menstrual irregularities, dysmenorrhea and wind evil.

Grass carp has the functions of warming the stomach, flattening the liver, dispelling wind, etc., and is a health food that replenishes deficiency in temperature.

Dace has the functions of strengthening muscles and bones, replenishing the stomach and appetizing, invigorating blood and inducing qi, and chasing water and dampness.

Silver carp has the functions of warming and benefiting qi, warming the stomach, moisturizing the skin, etc., and is a warm and healthy food.

Freshwater fish have an earthy smell, mainly because du is the living environment of freshwater fish, that is, water quality, fish ponds and lakes are not strong in the fluidity of the water, resulting in more things of various decay and impurities, which is very suitable for the growth of microorganisms, so the water quality is poor, there is an earthy smell in the water, and the fish live in the water with an earthy smell, and the fish are naturally infected with an earthy smell. Some of the wild freshwater fish also have an earthy smell because the rivers they live in are polluted and the water quality has deteriorated.

The method is as follows: 1. You can add milk, rice vinegar and Shao wine to the soup;

2. Before stewing the fish, you need to wash the belly of the fish, put it in cold water, and then pour a small amount of vinegar and pepper into the water.

3. 25 grams of salt and 2500 grams of water can be used for the stove banquet to soak the live fish in the salt water, and then the salt water will be soaked into the blood through the two gills, and the earthy smell can disappear after 1 hour;

4. There are two white tendons on both sides of the carp's back, and the two white tendons need to be removed when slaughtered.

5. When killing fish, you can rinse the blood of the fish, and add onions, ginger and garlic and other seasonings when cooking.
