Dormouse
The edible dormouse was thought to be a special food in ancient Rome. It was eaten as an appetizer or as a dessert. When it was eaten as a dessert, it would be dipped in honey and poppy seeds. The Romans had a special place to keep dormice which was called a glirarium. Dormice are still eaten in Slovenia, and apparently also by the Mafia.  Dormouse fat was used by the Elizabethans to induce sleep.
