Milk is produced by Ibba's flock of sheep. A traditional wheel of pecorino cheese is made. Cheese flies are allowed to lay eggs in the cheese. After about 40 days, the cheese is infested with cheese flies and their larvae (maggots). The cheese is eaten by the maggots. The cheese is excreted by the maggots, transforming it into soft and creamy casu marzu. Finally, the cheese is eaten at special occasions such as weddings or birthday parties.
