The Leopard Tavern - What's Cookin'? Arancini anyone? Chefs - Any good arancini recipes?

In Malice Stalks the Leopard, we have Ysabella making arancini for everyone.  It's one of Amodeus's favorites.  What is arancini?  I'm asking any chefs to care to contribute their recipes or to explain their ingredients.  When I lived in Palermo and was doing archival research, I ate a lot of arancini.  Yummy!!!!
