Pecorino Siciliano cheese is made from sheep’s milk, as are all Pecorino cheeses.
The cheese may be sold fresh, or aged. Aged ones are allowed to age for a minimum of 4 months.
It is made in Sicily.
Young ones can be used as a table cheese. Aged ones can be used for grating and shaving.
Some makers (certainly at least the marketers) of this cheese claim that it was made during the time that Greeks lived in Sicily, before it even became part of Rome.
