Working with one slice of salami at a time, fold the salami in half over the brim of a shot glass.
Fold the next slice the same way and overlap the first slice along the brim. Continue with the remaining slices until the brim is completely covered.
Repeat these steps and work your way around the brim until no more slices can be added to the brim.
Turn shot glass over onto charcuterie board and release the rose from the glass.
Use different sized slices for smaller and larger roses.
