Calcagno is a traditional cheese produced on Sardinia and Sicily. The cheese is made from sheep's milk and ages from 3 to 10 months. It's produced by adding black peppercorns to the curd, and then the cheeses are drained in baskets and salted.
The baskets leave a distinct pattern on the rind. As it matures, the texture becomes grainy and flaky, while the flavors become pungent, spicy, and salty, with the typical flavor of sheep's milk. When young, it's recommended to serve Calcagno with roasted peppers, and when aged, it's usually grated over pasta or vegetables.
