Istrian Truffles

The world's most prized hidden treasure - found by dogs in the forest

What is it?

In Istria, the triangular peninsula at the top of Croatia, forests hide one of the world's most expensive and delicious foods: truffles. A truffle is a type of fungus (related to mushrooms) that grows underground beside the roots of oak and hazelnut trees. Istrian truffles are famous around the world, and finding them requires a very special skill - and a very good dog.

Truffles cannot be farmed easily - they grow where and when they want, always hidden underground. The only reliable way to find them is to train a dog whose nose is extraordinary enough to sniff out a truffle buried beneath 30 centimetres of soil. In Istria, truffle dogs are considered very valuable family members.

The Motovun Forest, near the river Mirna in Istria, is one of the most famous truffle-hunting spots in the world. In autumn and winter, families head into the forest with their dogs before dawn. When the dog sniffs and starts scratching at the ground, the hunter kneels down and carefully digs with their hands so as not to bruise the truffle.

The largest white truffle ever found - a record-breaker - came from Istria and weighed over 1.3 kilograms. It was auctioned for charity and fetched an astonishing sum. Even a small truffle the size of a golf ball can be worth more than a hundred euros because the flavour is so intensely earthy and unique.

Truffles are used very sparingly - just a few thin shavings over scrambled eggs, pasta or risotto are enough to perfume the whole dish. In Istrian restaurants, truffle dishes appear on menus from small village taverns to grand coastal restaurants, and everyone has their own favourite recipe.

Discussion prompts

  1. 01Dogs can smell things buried 30 cm underground that humans can't detect at all. What other things can animals do that humans cannot? What do you think we could learn from that?
  2. 02Truffles are very expensive partly because they are very hard to find. Can you think of other things that are expensive because they are rare or hard to make?
  3. 03The truffle hunters get up before dawn to go into the forest. What job would make you excited enough to get up before dawn?

Classroom activity

Hold a 'truffle hunt' in the classroom. Hide small objects (wrapped sweets, coins, erasers) around the room while the class waits outside. Give each group one clue: a scent (scratch-and-sniff, a cotton ball with a smell), a sound (tap twice when warm), or a map. Which method of searching is most effective?
