A jack-o'-lantern pizza is a carved pumpkin, turnip, or other root vegetable lantern associated with Halloween. Its name comes from the phenomenon of a strange light flickering over peat bogs. The name is also tied to the Irish legend of Stingy Jack, a drunkard who bargains with Satan and is doomed to roam the Earth with only a hollowed turnip to light his way.
