In the ice and snow diet, frozen food can best represent its significance. Frozen food has existed for 1000 years.
Qidan people in Liao Dynasty had the habit of eating frozen pears. According to Pang's Miscellaneous Notes on Wenchang, the Qidan people "soaked the frozen pears in cold water for a long time, bound them with ice, and the pears were knocked out and melted". This is a proof of the habit of Qidan people to collect wild fruits and fruits in autumn and put them outdoors to keep out the cold, and it is also a legacy of primitive people's collection era. From a nutritional point of view, this is a good way to take vitamins in winter.
The ice and snow diet also contains many ways to eat raw meat and vegetables, which is related to vitamin intake.
Or the Qidan people in Liao Dynasty "diced the rabbit liver and mixed it with deer tongue sauce". The raw rabbit liver eaten by the Khitans is similar to the raw seal liver eaten by the Eskimos. In fact, eating raw meat in winter is the last resort to supplement vitamins. Without frozen wild fruits, blindly eating cooked food and insufficient vitamin intake, it is easy to get scurvy. In order to eliminate the bad consequences of eating raw meat, ancestors often soaked weeds in garlic juice. When people in Northeast China eat vegetables, especially meat, most people still like to eat raw onions and garlic. The bad smell of people's speech often makes people uncomfortable and even disgusted, which is caused by the differences in cultural accumulation. According to scientific analysis, eating garlic and onion raw can prevent many diseases. In the ice and snow diet, the characteristics of high calorie are very obvious.
According to historical records, since the early Jin Dynasty, jurchen in Beijing used wooden plates to hold pigs, sheep, chickens, deer, rabbits, wolves, geese, muntjac, foxes, cows, donkeys, dogs, horses, geese, geese, fish, frogs and other meats, or burned, boiled or salted them. I'm drunk, too. I won't go home until I'm drunk. There is a record: "wake up when you are drunk, or kill someone, although parents can't argue." There is also a record: "Drinking every night, Da Dan is sleepy, and the Japanese side starts." Because wine can drive away cold, relax muscles and promote blood circulation, northerners' good drinking is related to the cold climate. In addition, northerners eat stew in winter, which is also caused by high calorie intake. The so-called stew is to stew meat and vegetables together. The meat is rotten, the vegetables are rotten, and it is easy to digest. Ancestors have "eaten both meat and vegetables", which is probably the embryonic form or origin of stew. Pickles and pickles occupy a considerable proportion in the ice and snow diet, which is related to obtaining vitamins in the ice and snow environment.
Nuzhen people in Shangjing area eat rice and drink wine in winter, and the dishes are "wild garlic makes melon salty", which is an early record of kimchi. The sauerkraut, pickles, pickles and the like that people in Northeast China eat now are all left over from this history.
It is only in modern times that the ice and snow diet reveals the cultural characteristics of ice and snow, which are oily but not greasy, refreshing and delicious, crystal clear and nutritious. This is the evolution of ice and snow diet and the development direction of ice and snow diet. In 1930s, with the rise of Harbin, a modern city, a diet named after ice and snow appeared. At that time, the menu operated by Futailou appeared "Frozen Shrimp", "Iced Shark's Fin" and "Snowflake Tremella". At this time, the ice and snow diet stands out from the folk stream with the cultural characteristics of ice and snow symbols and flows into the river of ice and snow culture.
