Ricotta is a boundary entry, set by heat and acid, not by microbes. On the summer pastures the whey left from malga cheese is heated in the copper vat to 80–90 °C, and magnesium sulphate, citric acid or a herbal "sitz" makes the whey proteins rise. The ricotta drains in cloth bags, is lightly pressed, dry-salted for one or two days and smoked over a wood fire for one or two days.
Total time across the recorded steps: 2 days – 4 days

Ricotta is a boundary entry, set by heat and acid, not by microbes. On the summer pastures the whey left from malga cheese is heated in the copper vat to 80–90 °C, and magnesium sulphate, citric acid or a herbal "sitz" makes the whey proteins rise. The ricotta drains in cloth bags, is lightly pressed, dry-salted for one or two days and smoked over a wood fire for one or two days. Made in 7 steps over 2 days – 4 days. The longest step, dry-salt, takes 24 h – 2 days (ERSA (Agenzia regionale per lo sviluppo rural…).
It is made on the summer pastures in the same copper vat as the malga cheese, and set with magnesium sulphate or the herbal sitz, a practice the ERSA sheet calls old and documented. Pressed harder and smoked longer, it becomes a drier grating cheese.
Fresh smokedLightly pressed and smoked one or two days; eaten within 2–3 days.
Da grattugia (for grating)Pressed harder and smoked longer; harder and drier, kept for months.
Safety
The ERSA sheet asks that the heating temperature, matched to the acidity, sanitise the ricotta, and that drying in the smokehouse lower moisture enough to stop unwanted microbes.
The ERSA sheet says smoked ricotta has always been made alongside malga cheese. It cites Giuseppe Faleschini's survey "L'Alpeggio in Carnia" (Regione Friuli-Venezia Giulia, October 1970), which describes a method with no real difference from today's. Rules on the use of high pastures go back to the Patriarchs of Aquileia (11th–15th centuries).
