London, Nov 10: Produced in Zasavica - one of Serbia's most famous natural reserves - the cheese, known as pule, is made from donkeys' milk and costs a whopping 800 pounds per kilogram.
It is said to take 25 litres of fresh donkey milk to make a single kilogram of the cheese, which the reserve claims is the most expensive in the world, the Daily Mail reported.
The white, crumbly cheese has been described as similar to Spanish manchego cheese, but with a deeper, richer taste.
Available in British supermarkets for a relatively cheap 13 pounds per kg, manchego is certainly the more frugal option.
The reserve also produces bottled donkeys' milk, which is said to have been a beauty secret of Queen Cleopatra. (ANI)
