It's almost the Spring Festival in the suburbs of Beijing, and it's midnight. I am really hungry. After searching for a long time, many eating places were closed, only to find that a small wine shop was still open.
Although the small restaurant is still open, most of the clerks and chefs also go home for the New Year. There is not much stock in the store, so they can only eat whatever they want.
So the store cooked peanuts, rose dates, cut some meat, and served a sesame paste mixed with Chinese cabbage.
Emperor Qianlong ate this homemade cabbage with sesame sauce and was full of praise. Since then, this dish has become famous, known as dried cabbage, and has also become a famous dish in Beijing.
Habitat of Chinese cabbage production area
Chinese cabbage was originally distributed in North China and widely cultivated in China. Cabbage is hardy, likes cold climate and is suitable for growing in cold season. If cultivated in high temperature season, it is prone to pests and diseases, or the quality is poor and the yield is low, which is not suitable for summer cultivation. Its low temperature resistance is very strong.
After the temperature reaches -3℃, if the temperature can be gradually increased, the growth can also be resumed, but after reaching -8℃, if the temperature continues to drop to about-1 1℃, the normal growth cannot be resumed and it will suffer from freezing injury. Chinese cabbage is suitable for planting in loam, sandy loam and black loess with rich organic matter, but not in sandy soil which is easy to leak water and feces, and even less in clay with poor drainage.
