DampRid is a moisture absorber that can be used to dry mushrooms. It is made of calcium chloride, which turns into a liquid when it has absorbed enough water. While it is not a recommended additive for mushrooms, some people have used it to dry their harvest by placing a layer of DampRid in a container, suspending a screen over it, and laying out the mushrooms on the screen. This process typically takes 24-48 hours. However, it is important to note that the effectiveness of DampRid depends on the environmental conditions and the surface area it is exposed to. Other methods for drying mushrooms include using a fan, oven, or desiccant packets such as silica gel or charcoal briquettes.

Fan drying mushrooms before using Damprid
Fan drying mushrooms before placing them in a container with Damprid can help reduce the amount of moisture in the mushrooms, thereby reducing the amount of Damprid required. It is recommended to fan dry mushrooms for at least 12 to 24 hours before transferring them to a container with Damprid to complete the drying process.
Setup for Fan Drying Mushrooms
To fan dry mushrooms, place the recently harvested mushrooms on a plate or tray in front of a circulating fan set to a low or high speed. Ensure that the fan is constantly blowing air towards the mushrooms. One suggestion is to use a Vornado model fan, which can fit nicely over larger Tupperware bowls, forcing the air directly down onto the mushrooms.
Duration of Fan Drying
The duration of fan drying can vary depending on the size and moisture content of the mushrooms, as well as the environmental conditions. Most sources recommend fan drying for at least 12 to 24 hours. However, some suggest that even 48 hours of fan drying may not be sufficient to completely dry the mushrooms, and additional time may be needed.
Advantages of Fan Drying
In summary, fan drying mushrooms for at least 12 to 24 hours before using Damprid is a recommended practice to reduce moisture and optimize the drying process. This technique can help reduce the amount of Damprid needed and prevent the mushrooms from becoming oversaturated.

Damprid storage methods
DampRid is a moisture-absorbing product that can be used to dry out mushrooms and protect against mould, mildew, and moisture damage. Here are some tips for using DampRid for mushroom storage and other storage applications:
Mushroom Storage with DampRid
When using DampRid to dry out mushrooms, it is important to first partially dry the mushrooms using a fan before placing them in a container with DampRid. This is because DampRid will turn into a liquid when it has absorbed enough water, and if too much water is present, it will become too watery to reuse. Place the mushrooms on a screen or plate in front of a constantly moving stream of air from a fan on a low setting for 12-24 hours. After this initial drying period, place the mushrooms in a sealed container with DampRid, ensuring that the mushrooms do not touch the DampRid directly. You can place a layer of paper towels, aluminium foil, or a screen between the mushrooms and the DampRid to prevent direct contact.
General DampRid Storage Tips
DampRid is also useful for eliminating excess moisture and odours in various storage areas. Here are some general tips for using DampRid in storage applications:
- Use DampRid in closets, garages, boats, RVs, campers, storage units, and other areas where humidity or odours may be a problem.
- Place the product on a flat surface in the desired location and remove the lid to activate it, leaving the safety cover in place.
- Keep all DampRid products out of the reach of children and pets.
- DampRid does not absorb standing water, only moisture from the air. If you encounter standing water, wear protective gear, including rubber boots, safety gloves, and eye protection.
- In high-humidity or high-temperature conditions, DampRid products will need to be replaced more frequently.
- When refillable DampRid products are full of water, pour out the liquid and refill with new crystals. For disposable products, discard them when the crystals are gone.

Damprid vs. silica gel
DampRid and silica gel are both desiccants used to dry out mushrooms. DampRid is made of calcium chloride and dissolves as it absorbs moisture, turning into a liquid when it has absorbed enough water. Silica gel, on the other hand, does not dissolve as it absorbs moisture and is made of silicon dioxide. Silica gel is a water absorber but is not a very good desiccant due to its limited capacity. It is useful for keeping dry items from picking up water in a closed container.
When it comes to drying mushrooms, some people prefer using DampRid because you only need one package, and it can be reused by drying it out in the oven. However, others find that it can cause taste issues and becomes messy as it turns into a paste when it absorbs moisture. On the other hand, silica gel won't turn to mush, so it's easier to dehydrate and reuse.
To dry mushrooms effectively, it is recommended to first fan dry them for about 24 hours to remove most of the moisture. Then, use a desiccant like silica gel or DampRid to finish the drying process. This two-step process ensures that the desiccant doesn't get too wet and can be reused.
Some people also use a rack or screen to place the mushrooms on during the drying process, which helps increase surface area exposure and improves airflow, resulting in quicker drying. Additionally, using a sealed container can help prevent the mushrooms from spoiling or losing their potency.
In summary, while both DampRid and silica gel can be used for drying mushrooms, they have distinct properties and advantages. The choice between the two depends on factors such as ease of reuse, cost, and personal preference.

Damprid and mushroom taste
DampRid can be used to dry out mushrooms and prevent them from rotting in long-term storage. It is important to note that the mushrooms should not come into direct contact with the DampRid. Instead, they can be placed on a rack or tray above it.
Drying mushrooms with DampRid can be done in several ways. One common method is to first air-dry or fan-dry the mushrooms for 12 to 24 hours before placing them in a sealed container with DampRid to finish drying. This process can be expedited by using a rack to increase the surface area of the mushrooms exposed to the DampRid. Another method is to place the mushrooms in a container with DampRid at the bottom, covered with a layer of paper towels, foil, or a screen, and then placing the mushrooms on top.
Drying mushrooms with DampRid will not make them taste bad. In fact, some people report that drying mushrooms with this method results in little to no flavour loss, aside from the typical minor flavour loss associated with some gourmet mushrooms.
To store dried mushrooms, it is recommended to use airtight containers or glass jars, in a cool, dark place. This will help maintain their potency and prevent rot for at least two years.

Oven-drying mushrooms
Drying mushrooms in an oven is a straightforward process. First, preheat your oven to 170 degrees Fahrenheit. Then, arrange your mushrooms in a single layer on a baking sheet. Place the baking sheet in the oven and bake for one hour. After an hour, flip the mushrooms and return them to the oven until they are completely dry and crisp, which typically takes about another hour. Once they're done, let them cool down and then store them in an airtight container. With this method, your mushrooms should last up to three months.
It's worth noting that some varieties of mushrooms don't dehydrate well and are better frozen, such as Chanterelles. Morels, lobsters, oysters, and pheasants back are examples of mushrooms that dehydrate well.
If you're looking for an even crispier texture, you can try fan-drying your mushrooms before placing them in the oven. Simply place the mushrooms on a plate in front of a constantly moving stream of air from a fan set to "Low." This will help remove the majority of the moisture before you even start baking.
Another method to enhance the drying process is to use a desiccant like DampRid. DampRid is calcium chloride, which turns into a liquid when it absorbs water. You can place your mushrooms on a rack above the DampRid to help absorb excess moisture. However, some people find that this method is not worth the effort and cost, as it can be a hassle to recharge the DampRid after each use.
Additionally, when drying mushrooms, it's important to ensure they are completely dry. The mushrooms should have a clear, crisp snap when you break them in half. If they bend, they need more drying time.
