2. It is said that in the last years of the Eastern Han Dynasty, disasters and plagues continued everywhere. Zhang Zhongjing, who retired in his later years, returned to his hometown of Nanyang in winter. He saw that the villagers on both sides of the Baihe River were all sallow and emaciated, and many people's ears were cold and hungry. What's more, some people died because they couldn't cope with this hunger and cold.
3. Zhang Zhongjing saw it in his eyes and felt pain in his heart, so he developed a prescription called "Quhan Joule Decoction", set up a big pot at the entrance of the village, and put this cold-dispelling herb and pepper powder into the pot to suffer. In order to increase nutrition, mutton is also released for cooking.
After that, I ordered people to take out these cooked ingredients and chop them up, wrap them into ear-shaped "charming ears" with dough, and then give them to the people after cooking, and each person will drink a bowl of broth. In this way, after people ate Joule and drank Quhan decoction, they were really hot all over, their ears were hot, and their frostbitten ears gradually scabbed.
5. Since then, people have been obsessed with Zhang Zhongjing's kindness of "Joule Soup for Eliminating Cold", so much so that he imitated his Joule Soup in winter solstice and packaged it into food, also known as "jiaozi" or "flat food" to keep out the cold and keep warm. Next, there is a folk saying that if you don't eat jiaozi on the winter solstice, you will freeze your ears. To this day, there is a folk song in Nanyang, Henan Province, which is called "jiaozi Bowl is run amok from winter to sun, and nobody cares about frozen ears." .
6. According to medical experts, the ears, nose, hands and feet are all at the nerve endings, with little blood flow. They are particularly afraid of cold in winter and have poor frost resistance. Ear is protected by adipose tissue except the earlobe, and the rest is only covered by cartilage, so it is the most cold-resistant organ among the five senses. Eating a steaming bowl of jiaozi can really drive away the cold and keep warm.
7. From the perspective of culinary science, the cooking method of cooking jiaozi with water (steam) as the medium only needs about 100, which can not only cook food, but also sterilize it, avoiding the generation of strong carcinogens such as benzopyrene under the conditions of barbecue and frying, and ensuring food safety. Moreover, the nutritional components of food will not be lost due to peroxidation or hydrolysis during cooking.
8. From the perspective of dietary structure, jiaozi's fillings are all wrapped in dough, which can realize the proper collocation of grains, vegetables, fruits and meat, and make the main and non-staple foods have reasonable collocation, rich nutrition, acid-base balance and a dietary pagoda structure.
9. From the point of view of nutrition, jiaozi cooked with water (steam) as heat transfer medium can fully decompose starch polysaccharide in food, which is beneficial to human absorption.
10, suitable for China people's stomach and eating habits. It conforms to the regimen of "moderate diet", "harmony of five flavors" and "harmony of skills".
