To Brush and Peel Truffles

Put some raw, fresh truffles into cold water; wash them well, changing the water, then take them out one by one, and rub the surfaces over strongly with a hard brush, and throw them as fast as they are done into clean water, drain; take them out again one by one, and remove with a small knife all those parts the brush failed to touch, then refresh them leaving them as little as possible in the water. Wipe the truffles on a cloth, and with the tip of a knife detach all the skin covering them, cutting it away as thinly as possible, put the truffles as fast as they are done into a saucepan with a well-fitting lid; put also the peelings into a saucepan, and keep them in a cool place while waiting to be used.
