Sanguinaccio!

The resident gourmand from Napoli, Marco (student in the same school as me), told me about Sanguinaccio. It's chocolate and pig's blood... can you imagine? And apparently it's absolutely delicious. He was telling me how his mother used to make it often, and as a kid he'd be scared because he'd open the refigerator and there would be a jar of pig's blood in there. But he claims that the taste is divine. Does anyone know more about this, or tried it before?? (p.s. I don't think they make the real ones in the US, and though they've apparently created a version without the blood...)
