It means the close relationship between dog days and old Beijing's food customs. It is said that this food custom is related to the production skills of vegetable farmers: at that time, agriculture was backward, there were no greenhouse facilities, and there were no more summer vegetables for the people. When the summer solstice fell, it was the time when vegetables were green and yellow, and because of the hot weather in the summer days in old Beijing, sweaty people were willing to cook some simple and light and refreshing food at this time, which led to the food custom of pancakes in the summer days.
"Three volts pancakes spread eggs". After the dog days in beginning of autumn, the weather began to turn cold. At this time, it is easy to catch cold if you eat "hot noodle soup" in sweat. Housewives stand in front of the stove and bake pancakes for their families.
In ancient times, cake was a general term for food made of grain and flour. It was not until the Tang and Song Dynasties that cakes began to become round pasta made of flour, and there were many kinds of cakes with stuffing, thousand-layer cakes, shortbread, home-cooked cakes and pancakes.
Although there are few big fish and big meat in the dog days of old Beijing, some of them are light and plain, but they are seasonal foods for people in time. With the development of the times and the improvement of people's living standards and health care concepts, the catering customs in the dog days in old Beijing tend to be more diversified and balanced in nutrition.
