In the 1940s, there was a captain in the United States of America, Captain Grey, who, as a child, very much loved to eat the fried bread made by his mother, but one day he discovered that the central part of the fried bread was not fully ripe because of the lack of time for the fried bread, so Gray's mother dug out the central part of the fried bread, re-fried it again, and found that the bread tasted better, and the mid-air bread, the donut, was born. Since doughnuts are fried with hot and hot oil, the trick is how to make them fully fertilized in a short period of time, and the smart way in which they are handled by their mothers, which is all the more evident in their care and love for their children。
