The name means “rotten cheese” in Sardinia, but that’s just half the story: casu marzu contains live maggots. The makers introduce the larvae to a decomposing wheel of pecorino to break down its fat and render it even softer and runnier.

It’s not the maggots, however—Customs bans soft cheese of any kind.
