Upon receiving your white truffles from Bianca Bruni you should unpack them as soon as possible, including removing them from their vacuum-sealed pouch.
Examine your truffles, indulge in the aromas, then wrap them in fresh paper towels to absorb moisture and keep your truffles dry. Next, place them in a sealed container in your refrigerator until you are ready to use them. If you are not using the truffles within 24 hours, be sure to check your truffles daily and switch out the paper towels with fresh ones daily to avoid any excess moisture issues. (If the paper towels are not switched at least every 24 to 36 hours, the truffles can potentially get moldy.
Keep in mind that truffles can lose up to 10% of their weight each day, so be sure to enjoy your truffles as soon as possible upon receiving them. This will ensure that you will be able to enjoy them at their best when their flavors and aromas are at their peak.
