Bone Cookies

I saw these cookies at Termini Brothers in the Reading Terminal Market in Philadelphia on Halloween. They were marked Osso di Morta, or Bones of the Dead--hard clove-flavored cookies baked as a traditional All Souls' Day (November 2nd) treat.

 

I've seen numerous variations on the spelling (Ossi di Morte, for example), and some recipes indicate that variations include hazelnut flavors rather than clove. It seems they are not common to all regions of Italy, and may be primarily Piedmontese.
