The truffle is a mushroom which grows underground: obviously, when picked, it is covered with soil. It is a good practice that those who market truffles, will sell them already cleaned and brushed on the surface. This is made first of all because of the truffle weight which affects the price. Moreover this allows who is buying the truffle to verify its quality. The soil can hide possible defects, and besides, it can carry insects or worms of various size which could damage the truffle.
For all these reasons, our fresh truffles are marketed already brushed. We don’t wash them because this process could threaten their duration in time. Few hours before serving it or using it as an ingredient, you will simply have to clean it gently but accurately with a soft bristle brush (you can use a shoe brush or a toothbrush obviously cleaned) wet with room temperature water. The white truffle can’t be submerged in water, cooked or boiled.
