Truffles first need to be carefully extracted from the ground, if you sell them fresh it is necessary to slightly clean them with a brush in order to partially remove the soil.
If you freeze truffles, first it is necessary to clean truffles under cold water with different brushes, dry them, lay them on a tray and freeze shock them by using a freezer with the possibility of extra quick freezing, with such a process the mushrooms stay much tastier.
Once frozen, they are vacuumed in nylon and a product declaration is placed on them.
