It was from the Renaissance onwards, and especially in France, that the black truffle regained its place in haute cuisine, consolidating itself as a essential ingredient at royal and European noble banquets.
The exclusive character of the black truffle has been maintained over time, and today it continues to symbolize elegance and culinary excellence, becoming an undisputed benchmark in international gastronomy.
Botanical characteristics and natural habitat of the black truffle
La black truffle belongs to the genus Tuber and is a ascomycete fungus underground, which develops its life cycle in symbiosis with the roots of certain trees, particularly oaks, holm oaks and hazelnuts, although it can also be associated with some types of pines and steppes (cistus). This relationship is known as mycorrhiza and is essential for its development, since the fungus and the tree exchange essential nutrients in a mutually beneficial way.
The black truffle prefers limestone soils and well-drained soils, rich in organic matter and with a slightly alkaline pH. They are found mainly in regions with a Mediterranean climate, with cold winters and temperate summers. Spain, France, and Italy account for the largest global production, with the provinces of Teruel, Soria, Huesca, Navarra, and Girona standing out for their truffle-growing tradition.
- Morphology: Globose to subglobose in shape, with a matte black peridium covered with pyramidal warts. Their size varies between 3 and 12 cm in diameter and their weight typically ranges between 20 and 200 grams, although exceptional specimens weighing up to 600 g can be found.

The recollection The discovery of the black truffle is one of the most fascinating aspects of the mycological world. Being a subterranean fungus, locating it is an art. Traditionally, pigs, especially females, were used due to their powerful sense of smell, although trained dogs are now preferred, as they are more manageable and do not eat the truffles they find.
The search process requires knowledge, intuition and a deep connection with the natural environment. Truffle hunters, along with their dogs, roam the forests in search of this prized fungus, which can sometimes also be detected by the presence of the so-called "truffle fly."
