Pecorino Romano

Pecorino Romano is one of Italy's oldest and most characterful cheeses, a hard, granular sheep's-milk cheese produced exclusively in the Lazio region under strict PDO regulations. Its sharp, assertively salty, tangy flavor comes from 100% sheep's milk and a minimum five-month aging period—longer for the grating grades. The cheese was a staple of Roman Legion rations precisely because it traveled well: hard enough to survive transport and naturally preserved by its high salt content. Today it remains the defining cheese of Rome's most celebrated pasta dishes. The distinctive black wax coating on PDO wheels dates to the 19th century and serves both protective and ceremonial purposes; beneath it lies a white-to-straw-yellow interior that becomes more crumbly and intense as it ages. When you grate it, the cheese fractures into slightly oily, pungent shards that melt readily into emulsified sauces without greasing out—a quality that makes it indispensable for cacio e pepe and carbonara. Note that 'Romano' in the name refers to the market (Rome) rather than manufacture: authentic PDO production comes from Lazio, not Sardinia, which produces Pecorino Sardo under its own protected designation.
