Description
Of the six main varieties of pecorino, all of which have Protected Designation of Origin (PDO) status under European Union law, pecorino romano is probably the best known outside Italy, especially in the United States, which has been an important export market for the cheese since the 19th century. Most pecorino is produced on the island of Sardinia, though its production is also allowed in Lazio and in the Tuscan provinces of Grosseto and Siena. Ancient Roman authors wrote about this cheese and its production technique.
