It's a cool November day near Bologna, Italy. We are strolling through the woods with truffle hunter Mirko Illice and his little dog, Clinto. Clinto runs back and forth among the oak trees sniffing the ground, pausing, and then running again. Suddenly, he stops and digs furiously with both paws. “Ah, he's found an Italian white truffle,” Mirko explains. “He uses both paws only when he finds one of those.” Mirko gently pulls the excited dog from the spot and pushes through the soil with his fingers. He extracts a yellowish brown lump the size of a golf ball and sniffs it. “Benissimo, Clinto,” Mirko intones. Though not the finest example of the species, Tuber magnatum—which grows only in northern Italy, Serbia and Croatia—Clinto's find will fetch a nice price of about $100 at the Saturday market.
