At a glance

Ewe milk with up to 30 % goat milk is set with lamb rennet paste at 38 °C, broken to rice-grain size and semi-cooked at 46 °C for 30 minutes. The cheeses are pressed by hand, dry-salted for two days, dried on wooden boards and ripened for 3–6 months. Made in 8 steps over 3.4 months – 6.7 months. The longest step, ripen in a cellar, takes 3–6 months (ARSIAL (Lazio regional agency for agricultura…).

Safety

Milk may be used raw. In a challenge study, E. coli O157 added to raw ewe milk was still detectable in pecorino after 90 days of ripening, so clean milk or pasteurising matters. The regional sheet notes that, as a PAT product, it may use the hygiene derogations allowed for traditional foods.

Hazards the sources name: Escherichia coli O157, added to raw ewe milk in a challenge study of Italian pecorino made by several methods, not this cheese; still countable at 60 days and detectable after 90 days of ripening.

History and sources

Every number is labelled with how it is known. How this atlas is made

Known from local oral tradition and traces in municipal archives, and sold in local shops and markets for at least 25 years. The sheet links it in part to the Pecorino del Pastore described in the Istituto di Sociologia Rurale's atlas of Italian cheeses.
