Similar to Sardinia's casu marzu, cacio marcetto a pecorino that has been infested with the larvae of cheese flies, who give it a wonderfully creamy texture. When they are done, the cheese is broken up and exposed to air; the grubs are removed and the cheese is stored in earthenware jars. It's a powerful, spicy cheese, mostly made in the province of Teramo. Slow Food Presidium.
