Harvesting Jelly Ear Mushrooms
Timing is key when harvesting jelly ear mushrooms. They are best collected when they are young and tender, as older specimens can become tough and less flavorful. Look for mushrooms that are still flexible and slightly translucent. Avoid harvesting those that show signs of decay, such as discoloration or a slimy texture, as these are not suitable for drying. Early morning after the dew has dried is an ideal time to harvest, as the mushrooms will be plump and hydrated. Be mindful of the environment and only harvest what you need, leaving some mushrooms to release spores and ensure their continued presence in the ecosystem.
Before drying, it’s important to clean the harvested jelly ear mushrooms properly. Gently brush off any dirt, leaves, or debris using a soft brush or a damp cloth. Avoid washing them with water, as excess moisture can make the drying process longer and less effective. If the mushrooms are particularly dirty, you can quickly rinse them in cold water and pat them dry with a clean towel. Inspect each mushroom for insects or damaged parts, removing any that are not suitable for drying. Proper cleaning ensures that the dried mushrooms will have a longer shelf life and retain their quality.
Once cleaned, the jelly ear mushrooms are ready for the drying process. Lay them out in a single layer on a drying rack, mesh screen, or clean towel in a well-ventilated area. Ensure they are not overcrowded, as good airflow is essential for even drying. If using a dehydrator, follow the manufacturer’s instructions, typically setting the temperature between 40-60°C (104-140°F). Alternatively, you can air-dry them in a warm, dry place away from direct sunlight, which may take several days. Properly dried jelly ear mushrooms will become brittle and easy to break, indicating they are ready for storage.
After drying, store the jelly ear mushrooms in an airtight container in a cool, dark place. Label the container with the date of harvest and drying to keep track of their freshness. When rehydrating for use in soups, stews, or stir-fries, simply soak them in warm water for 15-20 minutes until they regain their pliable texture.

Cleaning Before Drying
Before you begin the drying process, it's crucial to properly clean your jelly ear mushrooms to remove any dirt, debris, or insects that may be present. Start by gently brushing off any visible dirt or debris from the mushrooms using a soft-bristled brush or a clean, dry cloth. Be careful not to damage the delicate mushroom caps, as they can tear easily. If the mushrooms are particularly dirty, you can use a slightly damp cloth to wipe them clean, but avoid soaking them in water, as this can cause them to become waterlogged and affect the drying process.
After brushing or wiping the mushrooms, it's essential to rinse them thoroughly to remove any remaining dirt or debris. Fill a large bowl or sink with cold water and gently swish the mushrooms around, using your hands to help dislodge any particles. Be careful not to agitate the water too much, as this can cause the mushrooms to break apart. Change the water if it becomes too dirty, and repeat the rinsing process until the water runs clear. This step is crucial, as any remaining dirt or debris can affect the flavor and texture of the dried mushrooms.
Once you've rinsed the mushrooms, it's time to remove the tough, fibrous stems. Using a pair of kitchen shears or a sharp knife, carefully cut the stems as close to the cap as possible, leaving only the tender, ear-shaped caps. Discard the stems or save them for making mushroom stock. If the caps are particularly large, you can cut them in half or into smaller pieces to promote even drying. Be mindful of any discolored or damaged areas on the caps, and trim them away as needed.
Before drying, it's a good idea to give the mushrooms a final inspection to ensure they're clean and free of any defects. Check each cap for signs of discoloration, damage, or insect damage, and remove any affected pieces. You can also use this opportunity to sort the mushrooms by size, which will help ensure even drying. Smaller pieces will dry more quickly than larger ones, so it's essential to keep them separate to avoid over-drying or under-drying.
After cleaning and inspecting the mushrooms, it's crucial to blot them dry with a clean, absorbent towel. Gently press the mushrooms between the towel to remove any excess water, being careful not to squeeze or wring them, as this can cause damage. You can also use a salad spinner to remove excess water, but be gentle to avoid tearing the delicate caps. Once the mushrooms are blotted dry, they're ready for the drying process. Remember, the goal of cleaning before drying is to ensure that your jelly ear mushrooms are free of dirt, debris, and excess moisture, which will help preserve their flavor, texture, and quality during the drying process.

Air Drying Techniques
Air drying is one of the simplest and most traditional methods for preserving jelly ear mushrooms (also known as wood ear or cloud ear mushrooms). This technique relies on natural airflow to remove moisture from the mushrooms, ensuring they remain lightweight, crisp, and shelf-stable. To begin, clean the mushrooms by gently brushing off any dirt or debris using a soft brush or cloth. Avoid washing them with water, as excess moisture can prolong the drying process and increase the risk of mold. If necessary, use a slightly damp cloth to wipe away stubborn particles.
Once cleaned, prepare the mushrooms for drying by slicing them into uniform pieces. This step is crucial because it exposes more surface area to the air, speeding up the drying process. Aim for slices about ¼ to ½ inch thick, depending on the size of the mushrooms. If the jelly ears are small, they can be dried whole, but larger ones benefit from being cut. Lay the slices flat on a drying rack, ensuring they do not overlap, as this can trap moisture and lead to uneven drying.
Choose an appropriate drying location with good airflow and low humidity. A well-ventilated room, a covered porch, or a shaded outdoor area works best. Direct sunlight should be avoided, as it can cause the mushrooms to harden or discolor. If indoor drying is preferred, place the rack near an open window or use a fan to circulate air around the mushrooms. The ideal temperature for air drying is between 60°F and 70°F (15°C to 21°C), as higher temperatures can cook the mushrooms instead of drying them.
Monitor the drying process regularly to ensure the mushrooms dry evenly and completely. Depending on humidity levels and airflow, air drying can take anywhere from 3 to 7 days. The mushrooms are fully dried when they feel crisp and brittle, with no signs of moisture or softness. To test, snap a piece in half—if it breaks easily, it’s ready. If it bends or feels pliable, continue drying for another day or two.
Finally, store the dried jelly ear mushrooms in an airtight container in a cool, dark place. Properly dried and stored mushrooms can last for several months, if not longer. Before using, rehydrate them by soaking in warm water for 15–20 minutes until they regain their chewy texture. Air drying is an energy-efficient and cost-effective method that preserves the mushrooms’ flavor and nutritional value, making it an excellent choice for home preservation.

Using a Dehydrator
After preparing the mushrooms, arrange them in a single layer on the dehydrator trays. Ensure the pieces do not overlap, as this can prevent proper air circulation and result in uneven drying. Depending on the size of your dehydrator, you may need to work in batches. Set the dehydrator to a low temperature, typically between 125°F to 135°F (52°C to 57°C). Jelly ear mushrooms are delicate, and a higher temperature can cause them to become tough or lose their texture. The drying process usually takes between 6 to 12 hours, but this can vary based on the thickness of the slices and the humidity in your environment.
During the drying process, it’s essential to periodically check on the mushrooms to ensure they are drying evenly. Rotate the trays every few hours to promote uniform drying, especially if your dehydrator has hot spots. The mushrooms are fully dried when they become crisp and brittle. You can test this by bending a piece; if it snaps easily, it’s ready. If it bends without breaking, it needs more time in the dehydrator. Properly dried jelly ear mushrooms should have a light, almost paper-like texture.
Once the mushrooms are completely dried, remove them from the dehydrator and let them cool to room temperature. Store them in an airtight container, such as a glass jar or vacuum-sealed bag, to protect them from moisture and air. Label the container with the date to keep track of their freshness. When stored correctly, dried jelly ear mushrooms can last for up to a year. To rehydrate them for cooking, simply soak them in warm water for 15 to 20 minutes until they regain their pliable texture.

Storing Dried Mushrooms
Drying jelly ear mushrooms (also known as wood ear or cloud ear mushrooms) is an excellent way to preserve their unique texture and flavor for extended periods. Once properly dried, storing these mushrooms correctly is crucial to maintain their quality. Dried jelly ear mushrooms should be kept in a cool, dark, and dry environment to prevent moisture absorption, which can lead to spoilage or mold growth. A pantry or cupboard away from heat sources like stoves or ovens is ideal. Ensure the storage area has good air circulation to avoid humidity buildup.
The choice of container is equally important for storing dried jelly ear mushrooms. Airtight glass jars or food-grade plastic containers with secure lids work best, as they protect the mushrooms from air and moisture. Avoid using paper bags or loosely sealed containers, as they do not provide sufficient protection. If using glass jars, store them in a dark place or wrap them in a cloth to block light, as prolonged exposure can degrade the mushrooms' quality. For added protection, include a silica gel packet in the container to absorb any residual moisture.
Before sealing the container, ensure the dried jelly ear mushrooms are completely cool and free of any moisture. Even a small amount of dampness can lead to mold or spoilage. Label the container with the date of storage to keep track of freshness, as dried mushrooms can last up to a year when stored properly. If you live in a particularly humid climate, consider storing the container in the refrigerator to provide an extra layer of protection against moisture.
For long-term storage, vacuum-sealed bags are an excellent option. Vacuum sealing removes all air from the package, significantly extending the shelf life of the dried mushrooms. If a vacuum sealer is not available, use the water displacement method to remove as much air as possible from a zip-lock bag before sealing. Store these bags in a cool, dark place or in the freezer for maximum longevity. Freezing does not affect the texture or flavor of dried jelly ear mushrooms and can keep them viable for several years.
Regularly inspect your stored dried jelly ear mushrooms for any signs of spoilage, such as off odors, discoloration, or mold. If any issues are detected, discard the affected mushrooms immediately to prevent contamination of the entire batch. Proper storage not only preserves the mushrooms but also ensures they are safe and ready to use in soups, stir-fries, or other dishes whenever needed. With the right techniques, you can enjoy the unique benefits of jelly ear mushrooms year-round.
