As a nutritionist who grew up eating fish and shrimp, let me answer this question! Opium fish head, chicken feet, pig feet ... these ingredients all have a common feature. Pay attention to these problems, and you will understand why opium fish heads are often seen in restaurants and restaurants, but where are the salmon with higher content and fat in protein? This fish head is imported, mainly from Russia and North China. All the fish bodies are sold abroad, and the head and tail are scraps. Foreigners don't eat, only people eat. So these fish heads and tails, which were originally discarded as garbage, were imported to China and served on the dining table.
It is actually the head of a Greenland flounder. This species is distributed in both the Atlantic Ocean and the Pacific Ocean, so it is not accurate to say that Atlantic flounder is more delicious than Pacific flounder. Why are all the dishes in the restaurant fish heads? The fish head and tail of Greenland flounder are commercial raw materials, and the raw material imported by importers is fish head. Meat ages easily. Another way to eat is to burn soup, fish head tofu soup, fish head is not fried, directly put it in water, and put onion and ginger cooking wine. After boiling for 20 minutes, cut the tofu into cubes and pour it down. When the water boils, you can eat. Eat it while it's hot, and put salt at last. It's better than the soup of fat fish, and the soup made of salmon head is also delicious.
How do you understand this kind of thing? Europeans don't eat fish heads and fish tails, while China people like to eat fish heads and fish tails, so adjust them to suit their own needs. You can also do the opposite: selling leftovers that Europeans don't eat to China is bullying China people and ethnic discrimination.
