Pecorino Sardo (Sardinian Pecorino or Fiore Sardo) is an Italian cheese made exclusively from sheep's milk, particularly the milk of Sardinian sheep breeds. Pecorino Sardo cheese is recognized with a PDO status, ensuring its production adheres to traditional methods on the island of Sardinia. It is a semi-hard cheese with a smooth, slightly crumbly texture. The texture and flavour can vary depending on the ageing period. The ageing period can range from several months to over a year. Pecorino Sardo has a slightly nutty and sweet flavour, making it milder and less salty than Pecorino Romano.
Pecorino Sardo is used in various dishes and as grating cheese for pasta and soups. It pairs well with Sardinian wines, fruits, and traditional Sardinian breads.
