Bakers and street vendors would often sell bagels stacked on long sticks or strung on a long rope.
Some people believe that the holes in donuts allowed them to be sold in a similar way.
So what happens to all those donut holes that are cut out of the dough?
Many people believe that those pieces of cut-out dough are what are used to make donut holes, which are those little round donut pieces that so many kids love to eat with milk.
In truth, though, many donuts with holes don't actually have any dough cut out of them to make their shape
The donut holes you buy at the bakery or grocery store are usually made out of dough simply cut into small squares!
