Raw ewe milk, sometimes with goat milk, is warmed over a wood fire in a copper caccavo to about 37–38 °C and set with kid and lamb rennet in about 30 minutes. The rice-size curd is pressed into wicker baskets, which are dipped for 4–5 minutes in boiling scotta left from ricotta making to form an even rind. The cheese is dry-salted and ripened from 2 months to about a year.

Raw ewe milk, sometimes with goat milk, is warmed over a wood fire in a copper caccavo to about 37–38 °C and set with kid and lamb rennet in about 30 minutes. The rice-size curd is pressed into wicker baskets, which are dipped for 4–5 minutes in boiling scotta left from ricotta making to form an even rind. The cheese is dry-salted and ripened from 2 months to about a year. Made in 7 steps over 2.1 months – 12 months. The longest step, ripen and treat with oil and vinegar, takes 2–12 months (ONAF (Organizzazione Nazionale Assaggiatori F…) and runs at 8–10 °C (ONAF (Organizzazione Nazionale Assaggiatori F…).
The milk is heated over a wood fire in a copper caccavo, and the basketed cheese is scalded in hot whey from ricotta making to shrink the paste and form an even rind.
Rind
Treated with oil and vinegar, fairly thick, wrinkled with basket marks, golden to brown
Made from raw milk. In a challenge study, E. coli O157 added to raw ewe milk was still detectable in pecorino after 90 days, so clean milk matters and ripening alone did not remove it. ANSES, the French food safety agency, says Listeria and enterohaemorrhagic E. coli in raw-milk cheeses can kill. It advises pregnant women, people with weak immunity, people over 65 and young children to avoid raw-milk cheeses, except cooked pressed cheeses such as gruyère or comté. ONAF classes this one as an uncooked paste. It adds that raw-milk cheese well cooked, as in an oven dish, no longer poses a risk.
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.
The Regione Campania page (updated 13 March 2015) says that for centuries the shepherds of Monte Marzano have filtered the milk and heated it over a wood fire in a copper caccavo, and that the method has passed from father to son. ONAF adds that the cheese is known to have been made the same way for at least 25 years, from local testimony gathered for the traditional-product listing, and that it is on the Campania list of traditional agri-food products.
