Casu Marzu

(Casu Modde, Casu Cundídu, Casu Fràzigu, Formaggio Marcio, Putrid Cheese, Rotten Cheese)

IT IS ILLEGAL TO SELL AND CONSUME THIS CHEESE DUE TO HEALTH RISKS. Casu marzu is a controversial Italian sheep’s milk cheese originating from Sardinia. The cheese is derived from the Pecorino family of cheeses and has a soft-ripened texture with a natural rind.


In English, casu marzu means rotten cheese, referring to live insect larvae (maggots) which can be found in it. After the fermentation process, larvae are introduced to the cheese, promoting decomposition and breaking down the cheese’s fats.


As a result, the texture of this notorious cheese becomes very soft. Casu marzu is typically cut into thin strips and spread on pane carasau, and it is recommended to pair it with a glass of strong red wine, but only if you find the cheese on the black market as it is illegal in the EU.


Just make sure to cover your eyes while eating casu marzu, because the maggots can leap up to 6 inches off the cheese.
