Chocolate Truffle

Now, as for the expiration of truffles, unopened and refrigerated, they typically can last up to a week, but it is always best to consume them as soon as possible to enjoy their full flavor potential. If you've purchased truffles vacuum sealed, they can last in the fridge up until the expiration date printed on the package. Once a truffle is opened or cut, its lifespan goes down significantly, lasting usually around 2-4 days. And as for freezing, truffles can be stored in the freezer, though this isn't commonly done due to the loss in aroma and flavor. But if you choose to, they can last up to 6 months.

To know if your truffle has gone bad, there are a few things you need to look out for. First, smell it. Truffles should smell musky and earthy, but if the aroma is too strong and unpleasant, it's an indication that it might be off. Also, check the texture. Fresh truffles should have a firm consistency. If it feels slimy or spongy, it's past its prime. Lastly, the color - black truffles should be jet black, and white ones should be off-white to slightly yellowish. Any sight of green or brown molds is a sure sign the truffle has spoiled.

• Stored truffles individually wrapped in a paper towel in an airtight container in the fridge. The paper towel absorbs moisture that might cause them to become slimy. Replace the paper towel once damp. • Don't wash truffles until you're ready to use them, as excess moisture can speed up the spoiling process. • If you have a lot of truffles to store, you can consider freezing them - but remember it's not the ideal scenario as it does lessen their flavor and aroma. Bury the truffles in rice or freezer-safe salt in an airtight container before popping them in the freezer. This helps absorb additional moisture and protects the truffle. • Use up fresh truffles as quickly as possible to enjoy their best flavor and aroma.
