Truffle black underground

Black truffle, the diamond of cuisine, grows underground in symbiosis with tree roots such as oaks and hazelnuts.

About this subject

The black truffle (Tuber melanosporum) is a highly prized hypogeous fungus in gastronomy, known for its intense aroma and earthy flavor. It thrives in temperate regions of Europe, mainly in southwestern France (Périgord), Italy (Piedmont and Umbria) and Spain (Teruel). The fungus forms a mycorrhizal relationship with the roots of trees such as oak, hazel and linden, growing at a depth of 5 to 30 centimeters in calcareous soil. Harvesting occurs between December and March, traditionally with trained sows or dogs that locate the ripe scent. The high price, which can reach thousands of euros per kilo, is due to the difficulty of cultivation, seasonality and demand from starred restaurants. Black truffle is used fresh, shaved over dishes like pasta, eggs and risotto, or in flavored oils and butters. Trufficulture, controlled cultivation, began in the 19th century and today produces about 80% of the world's black truffles, with inoculated trees in specific orchards, but production is still unpredictable, depending on climate and soil.
