Truffles are mostly underground fungi that are so rare that a truffle hunter with a dog will find few of these delicacies in a day. This makes them an expensive delicacy that is not always available for purchase. You can preserve truffles by drying them and thus make them last longer without the taste suffering too much.

Store truffles properly
Once harvested, the mushrooms gradually lose their flavor through oxidation. The higher the temperature, the faster this happens. Therefore you should always store truffles in a cool, dark and dry place, if possible in the original packaging. The coldest part of the refrigerator is ideal.
Dry truffles yourself
Truffles can be kilned very well and can then be kept for many months:
- Put the mushrooms on a plate and cover the delicacy with a dark-colored tea towel.
- Place the truffles in an airy, shady spot.
- Change the towel every day and turn the fungus over so it doesn't start to get moldy.
- Drying takes between four and eight days.
Dehydration with silica gel
Drying truffles is much easier if you use silica gel for this:
- Use a tight-fitting container with a small elevation, such as an inverted bowl, in it.
- Sprinkle a fine layer of silica gel inside the can, but not on the ridge.
- Place the truffles on the rise and put everything in the fridge.
- Replace dampened gel regularly until the fungus has dried.
Vacuum dry truffles
Then pack the completely dried mushrooms airtight with a vacuum sealer. Stored cool and dark this way, they will keep for about a year.
tips
The dried truffles can easily be frozen. Put the delicacy in portions in plastic wrap, vacuum and place the mushrooms in the freezer. Preserved in this way, the specialty can last for several years.
