The "white truffle" or "trifola d'Alba" comes from the Langhe and Montferrat areas of the Piedmont region in northern Italy and, most famously, in the countryside around the cities of Alba and Asti; in Italy it can also be found in Molise, Abruzzo, and in the hills around San Miniato, in Tuscany. It is also found on the Istria peninsula, in Croatia in the Motovun forest along the Mirna river, and in Slovenia along the Dragonja and Rizana river, as well as in the Drome area in France.
Growing symbiotically with oak, hazel, poplar and beech and fruiting in autumn, they can reach 12 cm diameter and 500 g, though are usually much smaller. The flesh is pale cream or brown with white marbling. Italian white truffles are very highly esteemed and are the most valuable on the market: The white truffle market in Alba is busiest in the months of October and November when the Fiera del Tartufo takes place. In 2001, the Tuber magnatum truffles sold for between 1000–2200 USD per pound (2000–4500 USD per kg); as of December 2009 they were being sold at 14,203.50 USD per kilogram.
Giancarlo Zigante and his dog Diana found one of the largest truffles in the world near Buje, Croatia. The truffle weighed 1.31 kilograms and has entered the Guinness Book of Records.
The record price paid for a single white truffle was set in December 2007, when Macau casino owner Stanley Ho paid 330,000 USD for a specimen weighing 1.5 kilograms, discovered by Luciano Savini and his dog Rocco. One of the largest truffles found in decades, it was unearthed near Pisa, Italy and sold at an auction held simultaneously in Macau, Hong Kong and Florence. This record was then matched on November 27, 2010 when Ho again paid 330,000 USD for a pair of white truffles, including one weighing nearly a kilogram.The Tuber magnatum pico white truffle is found mostly in northern and central Italy, while the Tuber borchii, or whitish truffle, is found in Tuscany, Abruzzo, Romagna, Umbria, the Marche and Molise. Neither of these is as aromatic as those from Piedmont, although those from Città di Castello come quite close.
Truffles are rare. The white ones are only available a couple of months of the year, almost exclusively from one part of Italy, where they must be foraged by special pigs, and there are fewer of them, and of lesser quality, every year. They are, in short, the perfect luxury commodity, precious and getting more so all the time.
There's no question that white truffles have a unique aroma, a combination of newly plowed soil, fall rain, burrowing earthworms and the pungent memory of lost youth and old love affairs. The most eloquent was Alex Guarnaschelli of Butter, a highly fashionable restaurant in New York City that caters to a moneyed clientele. The way truffles smell is "disconcerting," she says. "It conjures up images of a locker room. But the aroma deceptively conceals their complex yet delicate taste. They are sublime." Guarnaschelli shaves them over risotto or mashed potatoes, and likes them a little warm; other chefs find a little creamy or buttery pasta the perfect vehicle. They are all as careful in their handling of it as a museum curator moving the Mona Lisa.
