HOW TO PRESERVE TRUFFLES
Truffles are perishable goods which must be kept refrigerated at all time.
TO ENJOY YOUR TRUFFLES AT THEIR BEST WE STRONGLY RECOMMEND CONSUMING THEM AS SOON AS POSSIBLE.
They best way to preserve truffles is to wrap them with paper towel and put them into an airtight container such as a glass jar or a sealed plastic bag or box.
Place them in the less cold part of your refrigerator which is usually the vegetable draw/tray.
Truffles will slowly lose water therefore it is necessary to change the paper towel every couple of days or whenever the paper is wet to touch.
In this way it is possible to preserve:
