- The harvesting season runs from November to March. Harvesting requires trained dogs (or, less commonly, pigs) that can detect its distinctive aroma underground.
Culinary uses:
- The black truffle is widely used in haute cuisine.
- It can be used raw, grated over pasta, risotto, eggs, or salads, but it also retains its aroma when cooked.

Distinctive feature:
The black truffle is also called the “black diamond” because of its high value and incomparable taste. It is more affordable than the white truffle Tuber Magnatum, but it is also a symbol of luxury and quality in gourmet cuisine.
