What is the truffle
The truffle is an hypogeum fungus, it is born and lives underground. Its fruit body resembles the shape of a tuber (hence the scientific name Tuber).
Where the truffle grows
It grows in the ground, in close contact with the roots of trees and arboreal plants (mostly oaks, holm oaks, poplars, oaks and lime trees), with which it develops a symbiotic relationship capable of bringing benefits to both the fungus and the plant.
The truffle is composed of an external rind (peridium), which, depending on the species and the type of soil in which it grows, can be smooth or wrinkled, and an internal fleshy mass (gleba) often marked by veins, whose color varies from brown to ocher, from gray to pink. Its perfume, persistent and unmistakable, develops only after maturation.
Frequently asked questions and curiosities
How long can I keep the fresh truffle?
The truffle is a very delicate product, and is subject to easy perishability. Preserving its aroma is therefore essential to guaranteeing a quality and successful dish.
It is possible to wrap the truffle in a cloth, and place it inside a glass jar. Store in the refrigerator for a few days, and remember that if the white lasts 3 days, the black can double to 6.
White lends itself badly to freezing, in fact it will lose most of its aroma. Also be wary of storage in rice, which would significantly change the consistency of your truffle.
What is the intense scent of the truffle due to?
The Truffle has an original and unmistakable smell. It is due to gases released by some bacteria that nest in the peridium, and varies according to the composition of the soil in which it matures.
To avoid damaging its scent, remember … never wash the truffle!
How do I know if the truffle is fresh?
When a truffle changes color, scent, texture, the decay process has already begun. The scent will remember ammonia, its consistency will become soft, and the color will no longer be uniform.
A fresh truffle will be hard and with undergrowth scents ranging from hay, chestnut, honey, garlic, and so on.
Romano Tartufi deals only with the first choice, produced at the height of their maturation and their organoleptic qualities.
How does the truffle search take place?
Although seen as a simple helper, the real protagonist of the truffle search is the dog.
There are many dog breeds available to the quarryman, the best known is certainly the Lagotto Romagnolo.
Usually the most appreciated grow near the roots of the Poplar.
Why is the truffle so expensive?

Italy is the second largest producer of truffles in the world, second only to China.
The truffle is the second most valuable and expensive food, second only to caviar.
What changes between white truffle and black truffle?
From an organoleptic point of view, the two varieties are very similar. However, white is typically used raw, while black is also well suited for cooking.
The cost difference is due to the lower presence of the white variant on the territory, which develops only in a short period of the year, provided that the climatic conditions have been favorable.
