Truffles grow all over Europe, Asia, North and South America, but their most important habitats can be found in France, Italy and Istria. The most famous truffle habitat in Croatia is the valley of the Mirna river in Istria.
Truffles are picked only when they are ripe. Looking for truffles or the so-called hunt is led by an expert truffle hunter, and the truffles themselves are found by trained dogs with a perfected sense of smell. This used to be done by pigs, but today it is a rarity. Although pigs are very skilled at finding truffles, they often eat whatever they find.
