Cheese from Italy, Calabria
Rasco is a small, fresh, raw-milk cow cheese from Calabria, made entirely by hand from the milk of Podolica cattle. The milk is set with kid rennet paste at 36–38 °C, broken very coarsely with a fig-wood stick, packed into rush baskets, scalded in hot whey and dry-salted twice. It is eaten fresh, or smoked for about 20 days. Made in 6 steps over 20 days. The longest step, eat fresh or smoke, takes 20 days (ONAF (Organizzazione Nazionale Assaggiatori F…). Native lactic flora of the raw milk; no starter is added does most of the fermenting.

The name comes from "scraping the cauldron" (rascare la caldaia). Rasco was made from the curd scraped from the cauldron while the rest became pasta filata cheeses such as caciocavallo. The curd is never stretched; it is broken coarsely, packed into baskets and scalded in hot whey.
The regional derogation text names raw milk, wooden tools and rush baskets as hygiene risks and asks for milk checks and good hygiene practice.
Hazards the sources name: Staphylococcus aureus, named by the regional derogation text as a risk of raw milk.
Every number is labelled with how it is known. How this atlas is made
Landowners' herds of Podolica cattle made rasco as a prized gift for the Christmas holidays, ordering a set number from their herd foremen. The regional sheet cites Calabrian folk-tradition texts as evidence that it is over 25 years old. ONAF says the cheese has now disappeared, but the 2005 regional sheet describes it as still made.
