For many, cod from the ocean has always been a mystery.
The cod in large fresh supermarkets is often hundreds of yuan a small piece, so that many working people have the idea of unattainable. However, when you only need to spend 17 yuan to buy "gift from the deep sea of Arras Deepening Sea (M slogan)" at McDonald's, do you look confused, why is cod so cheap at this time?
Doesn't it feel like cod is natural and upscale?
The reason for this is that cod, like salmon, is a badly used and misused name. So, how do you figure out the various cod species? At present, there are also some articles or illustrations on the Internet, using biological classification to distinguish between various "cod", and to teach everyone to identify through the appearance of fish.

But I believe that after everyone reads it, in addition to the posture, they will still be dazed. Because, the various cod that everyone sees have become the following figure.
Can Ann tell who I am?
And the one in the figure below
You guess, you guess, you guess
And everyone may be more concerned about whether it is delicious or not, and whether the price is expensive or not.
Delicious is the last word
Therefore, Qiang Ge this time from the domestic e-commerce and major supermarkets can buy several kinds of cod, through the taste, nutrition and price and other factors to teach everyone to buy. Before you buy, you must look at the instructions on the packaging to see which kind of cod to buy.
[1] Real cod
Generally including Pacific cod, Atlantic cod, both belong to the cod order - cod family - cod genus, is recognized as the most "authentic" cod. The world's catch is not small, the total amount can reach about 2.5 million tons, so the price is often not expensive. It should be noted that the so-called "Norwegian Arctic Cod" promoted by the Norwegian Seafood Agency in the Chinese market in recent years is actually just Anthropocylic Cod produced in the Arctic Sea, which is essentially a real cod.
The flesh is a pale pink color
Taste: The protein content is very high, while the fat content is only 1%, so the taste itself is relatively rough, the taste is light, and its own umami taste is not very sufficient. In the kingdom of dark cuisine, the most common way for locals to eat it is to wrap it in breadcrumbs and fry them. Judging from my experience in cooking, my Greater China braised cooking method may be more suitable for it.
Reference price: 30-50 yuan / 500g
【II】 Narrow cod
The scientific name is yellow-lined narrow cod, and common names include Alaskan narrow cod and Mingtai fish (Japanese and Korean names). The world's largest sea catch of fish, the peak reached 9 million tons, in recent years stable at about 400-5 million tons, to know that the current national chicken production is only 13 million tons. Last year, the yellow-lined cod has been officially changed from the cod family to the cod cod genus. So the yellow-lined cod is also a "real cod"!
It is often made into crab meat sticks, fish patties, and fish fillets
Taste: In China, the most common method of yellow line narrow cod is to grind into meat paste and make crab meat sticks (yes, it is the crab meat stick you use to make hot pot). In addition, McDonald's McAdami Fort, KFC's Deep Sea Cod Fort and Cod Strips are also made from this fish. Narrow cod is rich in protein, delicate taste, melting in the mouth, delicious taste, price is not expensive, should be the most cost-effective cod, suitable for long-term purchase and consumption.
Reference price: 15-30 yuan / 500g
【3】 Silver cod/black cod
The scientific name is nudibranch, which belongs to the order Scorpiote, which can not be regarded as cod in any way in taxonomy, only because it has the same snow-white flesh color as cod, so it is given the name of "silver cod" by the Japanese, and slowly spread. Silver cod grows slowly, catches very little, and tastes well, so it is more expensive than real cod and is currently the most expensive "cod" on the market.
Creamy white and delicate
Taste: The fat content of this product is very high, generally up to 15%, so the meat is tender and firm. This fat is easily absorbed by the body and is rich in unsaturated fatty acids, which is very beneficial for preventing and reducing cardiovascular disease.
Reference price: 200-400 yuan / 500g
[4] French silver cod
Also known as antarctic small-scaled canine toothfish, it belongs to the order Perciformes - Antarctic fish family. Taxonomically , it is neither a member of the order Cod , nor a member of the " silver cod " class. In order to distinguish it from the silver cod, it is named according to the main production area (the main production area is in the Southern Indian Ocean, the Kergren Islands and the Croze Islands, which are both French overseas territories).
The flesh is snow-white, the texture is clear, and the scales are small
Taste: perennial active in the cold sea bottom, the pressure is large, the deep sea oil content is more, so the taste is delicate and delicious; the nutritional value is very high, rich in DHA (commonly known as "brain gold"), very suitable for pregnant women and adolescents to eat.
Reference price: 150-450 yuan / 500g
【5】 Oil fish
Also known as cod, dragon cod, round cod, belongs to the order Perch - Snake Mackerel family - heteroscaled snake mackerel genus. Due to the large amount of wax esters that cannot be absorbed by humans, oil-draining diarrhea will occur when eating too much. In the past, many merchants used this oil fish to pretend to be cod for sale, which was exposed by many media, but in recent years, the situation has been much better.
Carrefour supermarkets have exposed oil fish to be sold as cod
Taste: Although this kind of diarrhea does not cause harm to the body and has a certain amount of nutrition, Qiang Ge believes that this charming cheap goods have loose flesh, rough taste, and there is a risk of diarrhea, which is not worth the table at all, and more strongly despises the practice of bad merchants impersonating oil fish as cod.
Reference price: 10-20 yuan / 500g. Don't buy!
Finally, I would like to remind everyone that for the supermarket that only wants to indicate "cod", but does not want to indicate its real scientific name in its product description, and the price is very cheap, do not buy, because this is likely to be oil fish.
