“Cheese skipper flies, Piophila casei, lay their eggs in cracks that form in cheese, usually fiore sardo, the island’s salty pecorino. Maggots hatch, making their way through the paste, digesting proteins in the process, and transforming the product into a soft creamy cheese. Then the cheesemonger cracks open the top — which is almost untouched by maggots — to scoop out a spoonful of the creamy delicacy.” Casu marzu: The world’s ‘most dangerous’ cheese. (I suffer from maggot intolerance.)
