This hard cooked cheese is made with whole milk from pasture-grazed sheep, and has a particularly salty and slightly piquant flavor. Aged for at least 5 months, Pecorino Romano makes an excellent table cheese, particularly when combined with fresh vegetables and fruit, but after eight months of aging, it is mainly used for grating over classic Roman dishes such as Bucatini all’Amatriciana, Rigatoni alla Carbonara, Spaghetti Cacio e Pepe, and Tripe alla Romana.
The origins of Pecorino Romano can be traced back to the Roman Empire, when cheese processing methods were first described by some of ancient Rome's most important writers on agriculture: Varrone, Columella, Virgilio and Pliny the Elder. In 227 BCE, the production of this renowned cheese spread to the neighboring island of Sardinia, where even today almost 90% of Pecorino Romano is produced, while the remaining 10% comes from Lazio and the Tuscan province of Grosseto.
