With Da Rosario, Safina brings the purity of organic substances to his ardour for truffles with the launch of the first-ever USDA 100% organic truffle line. Prepare the dehydrator: Line the dehydrator trays with parchment paper to stop the truffle slices from sticking. Test for doneness: The truffle slices must be dry and crisp to the contact when they are ready.
