Though only around 13 species of truffles are of culinary interest, there are over 180 types of truffles found all over the world (many of which are inedible). In Piedmont, Italy, three of the most valuable, delicious, and rare truffles are:
White Alba truffles: The most expensive (around $3,000โ$9,000 per pound), rare, and valuable type of truffle, these cream-colored, knobbly treasures have an earthy umami flavor and are delicious shaved over pasta, steak, and scrambled egg. They grow in the forests around Alba, a town in the Piedmont region of Italy.
Bianchetto truffles: Known as the Albaโs little brother, ripe Bianchetto truffles are a rusty brown color and marbled with white veins. They have hints of garlic, cheese, and mineral notes, and complement risotto, smoked salmon, and game meats.
Black Norcia truffles: The most prized black truffle, black Norcia truffles (also known as black Pรฉrigord) have a fruity, nutty flavor with notes of cocoa; some say they taste like melting chocolate and even brandy. They are a common variety in Umbria, Italy.
