Truffle black underground

Black truffle (Tuber melanosporum): the black diamond of world cuisine, found underground in European woodlands.

About this subject

The black truffle (Tuber melanosporum), also known as Périgord truffle or black diamond, is a hypogean fungus that grows in symbiotic association with the roots of trees such as oak and hazelnut. Native to Europe, especially southwestern France (Périgord) and Italy (Piedmont), it is one of the most expensive and sought-after ingredients in world cuisine, costing thousands of euros per kilogram.

Harvesting takes place between November and March, traditionally done with trained pigs or dogs that sniff out the intense, earthy aroma. The unique flavor and penetrating smell result from volatile compounds like androstenone and dimethyl sulfide. Unlike common mushrooms, black truffles have no visible stem or gills; their surface is rough and dark, with white or grayish internal veins.

Although considered a symbol of luxury, truffle cultivation has expanded to other regions, such as Australia, New Zealand, and even South America, using controlled inoculation techniques. Still, scarcity and cultivation difficulty keep its rare status. In cooking, it is eaten raw or lightly heated, often in oils, pastas, or risottos, to preserve its delicate aroma.
