Mushrooms are a beloved ingredient in the kitchen, but they can also be a beautiful display piece. If you're looking to preserve mushrooms for display, there are a few methods you can try. One popular method is to dry them, either in an oven at a low temperature for several hours or using a food dehydrator. Dried mushrooms will shrink and become wrinkled, giving them a rustic and decayed look. You can also try vacuum drying mushrooms to help them retain their shape and speed up the drying process. Another option is to preserve them in a jar of high-proof alcohol or a liquid preservative, which will keep them looking fresh. For a more unique display, you can try encasing your mushrooms in plastic or liquid plastic, giving them a permanent and interesting appearance. With these methods, you can showcase the beauty of mushrooms in your own creative way.

What You'll Learn
Drying mushrooms in an oven
Preparation:
First, select fresh mushrooms that are not past their prime. Wipe them clean with a damp cloth or gently scrub them with a vegetable or mushroom brush under running water. Make sure to remove any remaining dirt as mushrooms tend to have dirt in their nooks and crannies. You can also slice the mushrooms into 1/8- to 1/4-inch thick pieces to ensure even drying. Thicker slices will take longer to dry.
Oven-drying:
Preheat your oven to a low temperature, ideally between 140°F to 175°F (60°C to 80°C). Spread the mushrooms on a baking sheet, ensuring they do not overlap. Leaving the oven door slightly ajar, place the baking sheet in the oven for about one hour. Then, flip the mushrooms over and return them to the oven for another hour.
Checking for dryness:
Remove the mushrooms from the oven and let them cool. The cooling period is essential, as they will continue to crisp up. After they have cooled, check if the mushrooms are completely dry. If not, return them to the oven for another 30 minutes, repeating the process until they are dry.
Storage:
Once the mushrooms are dry, allow them to cool completely before transferring them to airtight containers or glass jars. Label the containers with the mushroom variety and date. Store them in a cool, dry, and dark place, away from direct light and heat. Properly stored, dried mushrooms can last for up to a year.
Drying mushrooms in the oven is a simple process, but it requires attention and time. By following these steps, you can preserve the flavour and texture of mushrooms for future use.

Preserving mushrooms with glycerin
Preparing the Mushrooms
When harvesting mushrooms for preservation, it is important to cut them at the bottom of the stem where it enters the earth, rather than digging up or uprooting the mushroom. This is because mushrooms share a common root system, and uprooting can disturb this system. If the mushroom is growing on a tree trunk, you can carefully carve around the area to preserve the chunk of bark along with the mushroom.
Using Glycerin for Preservation
Glycerin, also known as glycerol or vegetable glycerin, can be used to preserve the freshness and plumpness of mushrooms. It is often used in combination with other preservatives like propylene glycol, antioxidants, and ethanol. However, it is important to note that glycerin can be expensive and may not be as effective for preserving fungal cells as it is for bacterial and human cell lines.
To preserve mushrooms with glycerin, submerge them in a solution of 10-20% glycerol. You can also add other ingredients like Lennox LB, chloramphenicol, and perlite, as per specific protocols. After submersion, hang the mushrooms upside down in jars, using toothpicks to keep them from falling in. This allows excess glycerin to drip off. For flat mushrooms, place them on a perforated pan or grate to let the excess glycerin drain. The mushrooms will have a glossy sheen and become hard after preservation.
Alternative Preservation Methods
There are several other methods to preserve mushrooms for display. One method is to use silica gel, a drying agent. Place the mushrooms in a container with a layer of silica gel crystals and cover them with additional silica gel. This process usually takes about 12 hours. Another method is vacuum drying, which involves using a food saver vacuum with a jar attachment to dry the mushrooms while retaining their shape. You can also try air drying the mushrooms for a day before displaying them in a book or jar. Additionally, high-proof alcohol or formalin can be used as liquid preservatives, although they may cause discolouration over time.

Freezing mushrooms
Freezing is a good way to preserve mushrooms. The process is straightforward, but some preparation is required to ensure the mushrooms retain their freshness, texture, and nutrients.
Firstly, it is important to select fresh mushrooms. Fresh mushrooms have a firm texture and pleasant earthy smell, and they are free of mushy or dark spots. The fresher the mushroom, the better it will keep in the freezer. Before freezing, mushrooms should be cleaned. Brush any visible dirt off the mushrooms or lightly rinse them in cold water and pat them dry with a paper towel. Do not soak the mushrooms, as this will make them mushy once cooked.
Next, prepare the mushrooms by chopping or slicing them into pieces, depending on how you intend to use them. Mushrooms can be frozen raw, but they may become mushy when thawed. To prevent this, it is recommended to steam blanch or sauté the mushrooms before freezing. Blanching destroys enzymes that can increase how quickly foods spoil, and it inactivates Listeria and Salmonella, improving food safety. Blanching times vary depending on the size of the mushroom, so it is a good idea to either sort them by size or cut them into similar-sized chunks before steaming. To prevent discoloration during blanching, soak the mushrooms in a mixture of 2 cups of water and 1 teaspoon of lemon juice for 5-10 minutes. Alternatively, steam them with 4 cups of water and 1 teaspoon of lemon juice. After blanching, place the mushrooms in an ice bath for the same amount of time that they were steamed. Sautéing is another option, which involves cooking the mushrooms in a small amount of hot oil or butter over medium-high heat for about 5 minutes, until they are tender but not squishy. Mushrooms can also be parboiled or cooked in other ways before freezing.
Once the mushrooms are prepared, place them on a parchment-lined baking sheet in a single layer, ensuring the pieces do not overlap. Flash freeze for at least two hours, then transfer the mushrooms to a freezer bag. Label the bag with the date, and store the mushrooms in the freezer for up to a year. Frozen mushrooms are suitable for cooked dishes such as soups, casseroles, stews, or pizza toppings. They can be added directly to dishes that will be thoroughly cooked, or they can be thawed overnight in the refrigerator before cooking.

Using a food dehydrator
Cleaning and Slicing the Mushrooms
First, clean the mushrooms with a damp cloth or paper towel. Avoid soaking the mushrooms in water as they will absorb it and become soggy. You can also use a mushroom brush for a thorough cleaning, especially with mushroom types that have lots of nooks and crannies. After cleaning, slice the mushrooms into thin pieces, ideally no more than 1/4 to 1/2 inch thick. Thicker slices will take longer to dry.
Preheating the Dehydrator
Turn on your dehydrator and preheat it to the desired temperature. The ideal temperature range for drying mushrooms is between 95°F and 135°F (approximately 35°C to 57°C). Lower temperatures, around 40°C, are recommended to preserve certain compounds in the mushrooms, such as psilocybin.
Arranging the Mushrooms on Trays
Place the mushroom slices on the dehydrator trays, ensuring they are evenly spaced and not overlapping. This arrangement allows for proper airflow and even drying. Make sure none of the pieces are touching.
Drying the Mushrooms
Place the loaded trays into the dehydrator and let the mushrooms dry. The drying time can vary from 4 to 12 hours, depending on the size, thickness, and moisture content of the slices. The mushrooms are adequately dried when they are crispy, brittle, and snap easily.
Cooling and Storing the Dried Mushrooms
Once dried, remove the mushrooms from the dehydrator and let them cool at room temperature to prevent condensation during storage. After they have cooled down, transfer the mushrooms to airtight containers, such as glass jars or plastic containers. Keep the containers in a cool, dry, and dark place to preserve the potency of the mushrooms. Properly stored dried mushrooms can last for several months, if not years.

Harvesting mushrooms for display
Mushrooms can be dried for display by baking them in the oven at 175° for about 2 hours. Dried mushrooms look very different from freshly picked mushrooms as they shrink and become wrinkled. If you are going for a rustic look, this method is perfect. You can spray the dried mushrooms with clear shellac to preserve them. If you want the mushrooms to look freshly picked, you can preserve them in glycerin. After submerging them, hang them upside down in jars, using toothpicks to keep them from falling. Alternatively, you can place them on a pan or grate with small perforated holes.
When harvesting mushrooms, cut them at the bottom of the stem where it enters the earth. Do not dig uproot the mushroom as they all share a common root system. If you have a mushroom on a tree trunk, you can carefully carve around the area to get a chunk of the bark as well as the mushroom.
Another method of preserving mushrooms is by freezing them. To do this, lightly sauté them in butter until they are just cooked or steam them whole for 5 minutes. For the best colour post-freezing, dip the mushrooms in a solution of 1 pint of water and 1 teaspoon of lemon juice before cooking. Once the cooked mushrooms have cooled, place them in a freezer-safe bag and store them in the freezer for up to 12 months.
Compared to freezing, drying mushrooms better preserves the quality of the fungi while indefinitely extending their shelf life. Dried mushrooms have an intense umami flavour and reconstitute well in soups, stews, sauces, or stir-fries.
