Bread-Bakers v106.n008.4

A very popular breakfast roll in Rome, Italy is called a "rosette". 
It is almost spherical, about the size of a fist, with a rosette 
pattern; i.e. five sections with a circle on top.  It is hollow 
inside, almost entirely without crumb.  The crust is soft, but quite chewy.

Can anyone provide a recipe for baking such a roll?
