How to buy truffles

Buying a truffle requires some attention, also because scams are not uncommon. At the time of purchase it is advisable to dwell not only on'appearance of the mushroom, which must be intact, but also on perfume; it would then be necessary feel it by touch.

The fresh truffle is compact and turgid, slightly elastic; a soft to the touch truffle is not usually a good mushroom, the same goes for an excessively hard truffle. It is also essential to know how to recognize the perfume; for example, the prized white truffle, when it is really good, has a delicate ed balanced scent of garlic, hay and honey; if there is only a strong smell of ammonia, it is absolutely not to buy.


In summary, buying a good truffle is not easy and you need to know the product. Some attention is also needed in the restaurant; considering that a grated one, equal to about 10 grams of truffle, costs at least € 30/40 per dish, it is advisable to ask the restaurateur to show the mushroom and have it grated by the staff, but at the table.

 

Collection periods

The collection period varies according to the species. The prized white truffle is harvested from 21 September to 31 January. In general, however, the truffle is a mostly autumnal product which, in the case of some varieties, can also be found throughout the winter.


The summer truffle or scorzone is an exception; it is harvested at the beginning of autumn but also from 31st June to XNUMXst August.
