Black Truffle (Tuber melanosporum)

Characteristics:

The black truffle has a shape that can vary from round to slightly oval, with a rough and irregular external texture. The external color is generally black or dark brown. Internally, the gleba is compact, black-brown in color, crossed by thin veins of white or light gray. The aroma is intense and persistent, with notes reminiscent of undergrowth, damp wood, and hazelnut.

Habitat:

The black truffle prefers calcareous, well-drained, and slightly alkaline soils. It grows in symbiosis with trees such as oaks, hazelnut trees, cherry trees, and poplars.

Production areas:

Mainly widespread in central and southern Italy, but also in the French Périgord, Spain, and some Eastern European countries. In Italy, the regions of Umbria, Marche, Tuscany, and Emilia-Romagna are particularly known for its production.

Harvesting period:

Harvesting runs from late November to late March, but the period of maximum ripeness is between December and February.

Use in cooking:

The black truffle is used in a wide range of dishes, from appetizers to first and second courses. It pairs beautifully with red meats, foie gras, aged cheeses, and eggs. It is also often used to flavor oils and salts.

White Truffle (Tuber magnatum Pico)

Characteristics and habitat:

The white truffle, also known as the "King of truffles", is the most precious and sought-after. It has a smooth and irregular outer surface, varying from pale yellow to brown. Internally, the gleba is ocher or light brown, with darker veins. Its scent is unmistakable: intense and enveloping with notes of garlic, onion, and aged cheeses. It grows in symbiosis with trees such as poplar, lime, and willow, in clayey or sandy soils.

Production areas:

The white truffle is typical of the Piedmont region, especially around Alba. However, it is also harvested in other Italian regions such as Tuscany, Marche, Emilia-Romagna, and Abruzzo.

Harvesting period:

The optimal harvesting period is from October to December.

Use in cooking:

Due to its delicate but distinctive flavor, the white truffle is generally consumed raw, cut into thin slices and placed on hot dishes such as risottos, tagliolini, carpaccios, and eggs.

Other types of truffles:

Also known as "scalable black truffle", it has a black wrinkled skin and a lighter gleba with white veins. The aroma is delicate, similar to that of the black truffle but less intense.

Winter Truffle (Tuber brumale):

Less prized than melanosporum, it has a rough black surface and a dark gleba with clear veins.

Burgundy Truffle (Tuber aestivum var. uncinatum):
