The unique Serbian donkey cheese enjoyed its white color, intensity and intense flavor, and it is not only delicious but also good for health, according to one of its manufacturers, Slobodan Simic.
However, there is only one "problem", which is that the price per kilogram of this cheese is one thousand euros (1130 dollars), which makes it the most expensive in the world.
Since 2012 Simic and a team of farmers have milked a herd of more than 200 donkeys living in the Zasavica Natural Reserve in northern Serbia.
Its milk has properties similar to breast milk, and Simic describes it as a treatment for a range of diseases, including asthma and bronchitis.
He says, "A human child can take this milk from the first day without diluting it," describing it as a "natural miracle."
The lack of scientific studies prevents the process of evaluating its health properties, but this milk is rich in protein, and the United Nations recognized it as a good alternative for those who suffer from allergy to cow's milk.
Simic comments on his flagship product: "No one in the world has made cheese of donkeys and no one can make it."
Donkey milk contains low levels of casein, which is an essential type of protein in the manufacture of cheese.
But a Zasavica employee discovered that donkeys' milk could be mixed with some goat's milk in order to form crumbled cheese blocks.
This mixture also helps in increasing the small amount produced by this animal, as the donkey produces less than one liter of milk per day, which is a small amount compared to 40 liters that the cow can provide.
The farm sells 6 to 15 kilograms of cheese annually to foreigners and tourists who visit it, according to Simic. The workers in the reserve also produce soap and drink of this milk.
Simic views his work as a way to protect the Balkan donkey, which is in dire need of replacing agricultural machinery. He explains: "We are maintaining the need for this animal, and now there is an increase in donkey farms and a rise in demand for these animals, which is very good for us and for the region."
In 2012, the unique producer made headlines after false rumors spread that Serbian tennis star Novak Djokovic had bought an enormous amount of donkey cheese, which the famous player later denied.
