Truffles are a delicacy in the USA, mostly because they don't grow in America. There are only a couple of places where you can find good truffles, including Croatia, France, Italy, New Zealand, and Australia. My family went to the Motovun forest in Istria, Croatia to truffle hunt. Our guide, Nickoli, told us all about it. The first thing is that you can't truffle hunt without dogs because they have a great sense of smell and can smell a truffle a meter deep in dirt. Truffle hunters used to hunt with pigs, but they ate the truffles that they found. There are two kinds of truffles, black and white, though I personally think they both smell like barf. They grow underground and are a type of fungus called Ascomycete. Truffles have to live close to a tree root, the biological term for this is ectomycorrhizal. The trees include Beech, Birch, Hazel, Hornbeam, Oak, and Pine.
As you know, dogs play a huge roll in truffle hunting, but they don't just learn overnight. It can take many years to train a dog to truffle hunt. Truffle hunters have different tactics to training their dogs. Any dog can become a truffle hunter, it doesn't matter about the breed. Our truffle hunter explained that he puts truffle on the mother's teat so when the puppy drinks the mother's milk it gets used to the taste of truffles. This is important because normally a dog doesn't like the taste of truffles. Any dog can learn how to hunt truffles it just takes time. When the dogs are puppies you teach them to use their noses to search for truffles by putting truffle on their toys or just hiding a truffle and urging them to find it. Our guide, Nikoli, usually takes three dogs out with him each session, and can spend two to three hour hunting for truffles with his dogs. When his dogs find something Nickoli tells the dog to dig. Then, when a truffle is shone the hunter looks over the truffle and then gives a little truffle to all the dogs. Even who did not contribute get a reward so all the dogs can learn to work together and be successful.
Truffles can be made into many different things including truffle oil, truffle paste, truffle with pasta, truffles with bread, salad with truffles, and truffle soup. The list is endless! People have been eating truffles for a long time, we still don't know a lot about them. We know that they are fungi and they grow near roots. We think we know what climate they grow in, but then the climate changes and it's the best truffle year ever. It's a hard job to have because sometimes the truffles don’t grow in a certain period of time and you have no income. Typically the white truffle is more expensive than the black. White truffles are typically 3,000 to 5,000 euros per kilogram and the black are usually around 2,000 euros. Truffle hunters sell truffles at markets and to restaurants. Some people even ship truffles to other countries.
