Fish Head in Sour Soup

"Kimchi" tastes very appetizing, and it is delicious whether mixed or fried. This is also a consensus shared by many Sichuan people and friends who like to eat kimchi. However, in the past, many people thought that kimchi was an unhealthy pickled food, and some even thought that it contained carcinogens. In fact, this is not the case. In recent years, nutritionists have conducted nutritional and physical analysis of kimchi. Tests have confirmed that eating kimchi will not only not cause harm to the human body, but will be beneficial to health and is a better health food.
Because kimchi produces a large amount of lactic acid bacteria after fermentation, it can help the human gastrointestinal system digest, kill harmful bacteria, and play an appetizing role. After fermentation, fresh vegetables not only lose very little nutrients, but also retain most of their vitamins.
In the past, people thought that kimchi contained carcinogens, because during the production process of kimchi, salting with salt and water would produce a large amount of nitrite. If the human body ingested too much nitrite, it would cause harm to the body and even cause cancer, because nitrite is a carcinogenic substance. Later, after experiments, it was found that during the brewing process of kimchi, the content and formation of nitrite would peak in the first 3-4 days. However, as the curing time went by, when the kimchi was cured for 5 days, the nitrite content would gradually weaken. After curing for 15-20 days, the kimchi would basically disappear through a series of chemical and physical reactions during the fermentation process, but most of the nutrients in the vegetables would still exist. Therefore, it was concluded that, Kimchi is a healthy and edible pickled food.
Through the above experiments, it has been proved that many friends in Sichuan who like to eat "bathing kimchi" should pay attention. It is an unhealthy way to eat. "Bathing kimchi" is actually a kind of kimchi made by quick marinating. It is kimchi that is eaten after marinating vegetables in old stock for a day or two. As you may not know, the nitrite content in kimchi is at its highest at this time, so you must not eat it any more. It is an unhealthy way to eat it. You must marinate the kimchi thoroughly for a long time. In fact, eating old kimchi is the healthiest way to eat it.
Today, kimchi and kimchi soup are used to make a dish that is most suitable for winter consumption, called "sour soup fish head". The method is as follows;
