Pule cheese

Pule cheese, or just pule, is a cheese made from the milk of Balkan donkeys from Serbia.

A distinctive dairy product of Serbian cuisine, pule is reportedly the "world's most expensive cheese", fetching 1,000 Euros per kilogram. In September 2013, the cheese was valued by a news source at $600 USD per pound. It is so expensive because of its rarity: there are only about 100 jennies in the landrace of Balkan donkeys that are milked for pule-making, each jenny must be hand-milked thrice daily, it takes 25 litres (6.6 gallons) of milk to create one kilogram (2.2 pounds) of cheese, and the cheese is then smoked.
