After cleaning the truffles with a soft brush, individually wrap each truffle separately with a fresh kitchen paper towel. Then, position these wrapped truffles within a pristine airtight container, such as a sealed flip-top jar. Every 24 hours, replace the paper towel and re-wrap the truffles. Return them to their container and keep them in the refrigerator. Repeat this cycle until you're prepared to incorporate them into your culinary creations.
