The white truffle is the rarest and most prized of the varieties. The scientific name is Tuber Magnatum Pico: magnatum, because it was destined for consumption by magnates, the great tycoons of the table, and Pico from the name of the Turin physician who first described its characteristics in 1788. Of all the types of truffles, this one can grow to the largest size. It is egg-shaped, yellow-white on the outside with a hazelnut beige on the inside, depending on how ripe it is.
This variety is far more common and found on the plains, in the hills and the mountains at shallow depths in clayey-limestone earth, near both broad-leafed trees and pines. It is small in size, has a smooth red-brown exterior and a light and very veined interior. It has a slightly garlicky taste and is therefore somewhat less prized.
Remember that to fully enjoy the flavour and aroma of the truffle, it should be eaten while still fresh. Although seasonal, they can be preserved. The most common manner is by freezing them, either whole or already grated. First, however, they must be carefully cleaned and dried.
You can even dry them in thin slices and then ready them for use by soaking them in warm water or milk. Some people preserve them in glass jars with a tablespoon of salt after having boiled them for at least an hour, depending on their size. But no matter how you conserve them, the flavour and aroma never quite compare to that of a fresh truffle.
