With Da Rosario, Safina brings the purity of natural substances to his ardour for truffles with the launch of the primary-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. When you have any questions or would like to buy our truffles or focus on wholesale costs, please get in contact.
