White Truffle

Where it grows

The white truffle of Alba — tartufo bianco — is harvested between October and December in a tightly limited geography centred on the Piedmont, Marche, and parts of Croatia, where the specific combination of host trees and sandy clay soil suits it. Unlike the black truffle it has resisted reliable cultivation and remains essentially wild-foraged with trained dogs.

How to recognise it

A pale tan to ochre, irregularly lobed tuber with a smooth (not warty) skin. Sliced open, the interior is pale brown with very fine creamy-white veins. The aroma is overpowering even at arm’s length — a heady mix of garlic, ripe cheese, methane, and honey.

Edibility & cautions

A choice edible and the most expensive mushroom on Earth, often selling at thousands of euros per kilogram in good years. Beware imported and chemically infused “truffle oils,” which use synthetic 2,4-dithiapentane and contain no actual truffle.

Culinary use

Always served raw, shaved at the table over warm fresh pasta, fonduta, or risotto. Heat destroys the perfume within seconds.
