the donut machine is most conveniently designed for its purpose to make the best presentable and properly cooked donut. Is also a delicious  tongue hole.

Answer 4

Well, its jsut a classic look. Why are hamburgers round?

But if you go to a Krispe Kreme and you see them make the donuts- it also sereves a purpse. After the donuts are frosted, they use a thin, wooden stick (kind of like a big chopstick), put it in the hole at an angle, and pull it out. It's better than using your fingers, cuz the icing woulnd't be properly coated, and the donut is hot!!!

Answer 5

So you can look through it whilst you're eating it at the same time???  Or you can put two on your eyes and pretend to wear glasses!
