This is an awesome comment.
As I said in a comment below su caggiu (or callu, it depends from where you are, we sardinians have a dialect for each village) is my preferred cheese, now I know more than before about it, thanks.
No, but you got the article right.
Caggiu means rennet or curd the substance that is used to transform milk into cheese, cheese translates as casu as in casu marzu (that could be translated as spoiled cheese).
My 2nd favourite cheese.
For those concerned about the maggots, they are born in cheese, eat cheese and shit cheese all their life as maggots, they are basically living cheese :)
