Casu axedu

Casu axedu is an Italian cheese hailing from Sardinia. The cheese is made from sheep's or goat's milk. After the curd has been shaped, it's often left to drain for 2 days before it's placed into brine, where it can stay conserved for a long time.

The process turns the soft and sweet cheese into an acidic and pungent one. When fresh, it's usually served as an accompaniment to vegetables and salads, but it can also be spread on bread. Once matured, the cheese develops a harder texture and can be grated over pasta dishes and soups.
