Is there any difference between a bun and a roll?
The Answer:

Technically there isn't, although in the U.S. the government distinguishes between them and bread, which has to weigh more per unit volume than buns or rolls.

But customarily we do use "bun" and "roll" to mean different things. A hard crust usually makes it a roll. It's also ordinarily a roll if it has a filling, although one person's cinnamon roll might be another's cinnamon bun, depending on where they live. In Britain, where a bun is round, sweet, and cake-like, the traditional Easter pastry is always a hot-crossed bun. American hot dogs usually come on a bun that's long and narrow, but
hamburgers are less particular about the name of that into which they are sandwiched.

The bottom line: eating too many rolls or buns will put fat in rolls ON your buns.

This is a great tip as it's something most of us don't use frequently. Make super-fine sugar by whirling granulated sugar in a blender or food processor until powdery.
