why a doughnut has a hole?

The hole in doughnut can be something to eat around or stick finger in, or peek through. But you can't hold it. And once you eat the doughnut, the hole is gone.


A machine puts the hole in a doughnut. It punches the doughnut out of a flat piece of dough, the way you cut out cookies with a cooky cutter. The doughnut, hole and all, is put in boiling oil. The oil bubbles through the hole and around the doughnut until it is puffy and crisp. Without a hole, a doughnut just wouldn't be a doughnut. It would be a round, flat doughy cake with a soggy center.
