Amatriciana sauce

Sugo all'amatriciana, or alla matriciana, also known as salsa all'amatriciana, is a traditional Italian pasta sauce based on guanciale, pecorino romano cheese, tomato, and, in some variations, onion. Originating from the town of Amatrice, the Amatriciana is one of the best known pasta sauces in present-day Roman and Italian cuisine. The Italian government has named it a traditional agro-alimentary product of Lazio and Amatriciana tradizionale is registered as a Traditional Speciality Guaranteed in the EU and the UK.
