A small pear-shaped pasta-filata cheese from Calabria concealing a heart of soft fresh butter, made from the raw milk of Podolica cattle on the Pollino, Sila, and Sibari plains; the sealed cheese shell preserves the butter for weeks without refrigeration, releasing a molten core of cream when the rind is cut at room temperature.
Born of shepherds' necessity to preserve fresh butter during transhumance across the Pollino, Sila, and Sibari highlands before refrigeration, Butirro seals butter inside a pasta-filata cheese casing to create a self-contained, shelf-stable unit. Produced across the provinces of Cosenza, Crotone, and Catanzaro using milk from Podolica cattle that graze the rich mountain pastures, it once circulated as barter currency at rural markets and is now recorded on Slow Food's Ark of Taste.
Cut through the pale golden rind and a soft knob of barely salted butter spills out; the outer cheese layer is gently tangy and springy while the butter core is cool, rich, and faintly sweet.
The pasta-filata process heats acidified curd to around 80°C and kneads it into a continuous casein network, forming an elastic, low-moisture shell with high acidity and low water activity that blocks microbial spoilage; the butter core is protected from oxygen and pathogens by this dense protein matrix, remaining stable for weeks; during curing the outer cheese slowly develops mild ester and oxidative notes while the interior butter stays fresh and sweet.
Variations
Manteca (Puglia): a closely related butter-core pasta-filata cheese with a firmer interior also called Burrino di Bufala when made with buffalo milk; Sorrento burrini from Campania are smaller and more delicately flavoured; buffalo-milk variants exist in parts of Campania and Molise.

Ingredients
Serves 6How it's made
7 steps · 1 hour
- 135 min
Warm raw Podolica milk to 37°C in a wide copper or stainless pot; add natural calf rennet and stir gently for one minute, then leave undisturbed for 30 minutes until a firm, clean-break curd forms.
- 225 min
Cut the curd into grape-sized pieces and heat slowly to 45°C while stirring continuously to firm the grains and expel the whey.
- 3300 min
Transfer the curds to a draining mat, pour off the whey, and allow the mass to acidify at room temperature for 4–6 hours, testing readiness by pulling a small piece in hot water until it stretches cleanly.
Watch outTest-stretch a piece in hot water — it's acidified enough only when it pulls into smooth shiny strands instead of tearing.
- 420 min
Submerge the acidified curd in water at 80°C and knead and pull it repeatedly with wooden paddles until it forms a smooth, shining, elastic ball—this is the pasta-filata stage.
Watch outWork the curd in the hot water until it turns glossy and elastic — this stretching is what seals the shell that will protect the butter.
- 510 min
Flatten the hot curd into a round sheet, place a walnut-sized lump of fresh lightly salted butter at the centre, and fold the curd over it tightly, pinching firmly to seal without air pockets.
Watch outFold the curd tightly around the butter and pinch the seam shut with no air gap, or the join splits and the butter leaks out in curing.
- 65 min
Shape the parcel into a pear with a narrow neck; tie the neck with natural cord and dip the cheese briefly in cold water to fix the shape.

Hang in a cool, well-ventilated room for 20–30 days until the rind turns golden and the cheese feels firm; serve at room temperature so the butter core softens before slicing.
