Doves from Emilia Romana

This is a rather complicated party dish from Emilia Romana, but it really does repay the effort and will amaze your friends whilst using very cheap ingredients. Do try it. You can get it all ready to cook, keep it overnight, and bake it for the party on the day. The Italians add sweetbreads to the mold—if you have a supply, try it. Just cook them slightly in melted butter first, then slice and layer them into the mold.
