The world of truffles

The truffle is an underground fungus: it develops in the soil, in association with the roots of certain plants. What we serve at the table is its fruiting body. The surface is called the peridium; the interior, crossed by veins, is the gleba. Knowing these two terms helps you observe the differences without stopping at color alone.

In cooking, there is no single “truffle flavor.” Species, ripeness, and freshness change the experience. The four varieties discussed here are a starting point: the world of truffles also includes other species, such as the brumale and the smooth black truffle. Photography helps you become familiar with their appearance, but it does not replace identification by someone who knows the product.

Tuber magnatum. It has a light, irregular surface in cream and ochre tones, with a veined interior. It is the truffle that many associate with the act of shaving thin slices over a freshly served dish.

Its season is autumn and early winter. For a first taste, choose a simple preparation: tagliolini, eggs, or a delicate base that leaves room for its aroma. The dish should complement it without becoming a competition of aromas.

Tuber melanosporum. The skin is dark and warty; the mature gleba has light veins against a dark background. It is one of the best-known expressions of Umbria’s truffle-growing tradition.

It is a winter variety. At the table, it invites you to explore warm, comforting preparations. When designing the dish, start with its character and keep the foundation clear: a few well-chosen ingredients help reveal its nuances.

Tuber aestivum. The name scorzone refers to its pronounced surface. The gleba tends toward hazelnut tones, crossed by light veins.

The relevant season is late spring and summer. It can be a pleasant way to approach truffles through everyday preparations. Don't expect the same aroma as the prized white truffle: appreciating the differences is part of the discovery.

Tuber borchii, also known as the marzuolo truffle. It is not a small, prized white truffle: it is a distinct species. Its aroma may have highly recognizable garlicky notes.

Between winter and spring, it offers another opportunity to discover fresh truffles. When pairing it, it is best to start cautiously and taste: a bold character finds balance when the other ingredients leave it room to shine.

Autumn–early winter: prized white truffle.
Winter: prized black truffle.
Winter–spring: bianchetto truffle.
Late spring–summer: summer truffle.

This is a general guide to seasonality, not a harvesting calendar. Authorized dates vary by region and may be updated depending on the year. Availability and ripeness are also affected by the climate: before buying fresh truffles, ask which species is available and where it comes from.

First choose the experience you want to have. Fresh allows you to get to know a species directly; a sauce is an already-composed recipe with its own balance; a condiment adds a final note. They are not interchangeable versions of the same ingredient.

For your first purchase, check the species name, format, and usage instructions. Do not choose based solely on color or size. A simple question for the seller - “how do you recommend serving it?” - may be more useful than an elaborate preparation.

Are bianco and bianchetto the same truffle? No, they belong to different species.
Is the black truffle always a winter truffle? No: the generic name may refer to species with different seasons.
Does a sauce reproduce the fresh truffle exactly? No: it should be understood as a preparation, taking all the ingredients into account.
