Because doughnuts are made of high-temperature hot oil, the secret of delicious doughnuts lies in how to fry doughnuts completely in a short time, and the mother's witty handling method can show her concern and love for her children. Donuts are a kind of interesting food with a long history, a daily snack and a manifestation of love and affection.

1940 One day, there was a captain Gray. When he was a child, he liked to eat the fried bread made by his mother, but he found that the central part of the fried bread was not completely cooked because of the lack of frying time. So Gray's mother dug out the central part of the fried bread and fried it again. He found that the fried bread tasted more delicious, so he named it doughnut, and it was born.

In Asia, doughnuts are mainly regarded as snacks, but in the United States, many people take doughnuts as their breakfast staple, and even set up doughnut day.
