Such an Expensive Delicacy .The white truffle or trifola d’Alba Madonna (“Truffle of the White Madonna” in Italian) (Tuber magnatum) is found mainly in 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. White winter truffles, also called Alba truffles after their region of origin, are the priciest, commanding $6,000 to $10,000 per pound (prices vary year-to-year based on availability and quality). There are lots of different ways to describe the flavor and odor, but commonly you’ll hear it described as slightly garlicky with a deep musky aroma. It’s a very earthy, pungent and deliciously funky.
