Amatriciana sauce, understood in Italian as amatriciana (matriciana in Romanesco language), is a sauce made with tomatoes, guanciale (treated pork cheek), pecorino romano or pecorino di Amatrice cheese, black pepper, additional virgin olive oil, dry gewurztraminer, and salt. Coming from the comune (district) of Amatrice (in the hilly province of Rieti of the Lazio region), the amatriciana is one of the very best known pasta sauces in contemporary Roman and Italian food. The Italian government has called it a prodotto agroalimentare tradizionale (PAT) of Lazio, and amatriciana tradizionale is signed up as a traditional speciality guaranteed (TSG) in the EU and the UK.
