You'll find the full recipe here. The thing that makes it perfect for a Halloween party is the skull-shaped baking pan, which you can find at many outlets online if you can't get one at a store near you. The payoff is the terrifying vision of a diner pulling the skull apart to dip it into marinara sauce. You can get a similar effect by drizzling the sauce over the skull. Bon appetit!
