Pule

Pule is the world's most expensive cheese. Originating from Zasavica Nature Reserve in Serbia, the cheese is made with the milk coming from Balkan donkeys, making the product extremely unique and rare. It takes about 25 liters of donkey milk to produce just 1 kilogram of this crumbly white cheese, but a jenny (a female donkey) can only produce 0.2 liters of milk.

Three times a day, these donkeys are milked by hand. The cheese has only 1% milk fat, and it also has anti-allergenic properties. It is usually sold at 1000 Euros per kilo, but Pule can even reach the price of 3, 4, or 5 thousand Euros per kilo.
