What You'll Learn

Thinly slice the mushrooms
Drying matsutake mushrooms is a great way to preserve them for future use. Matsutake mushrooms, also known as pine mushrooms, are highly valued in Japanese cuisine for their unique flavour and aroma. Before you begin the drying process, it's important to clean your mushrooms thoroughly. Use a soft-bristled brush to remove any visible dirt or debris, and ensure you have a sharp knife and a clean workspace to avoid any contamination.
Now, let's talk about thinly slicing the mushrooms. This step is crucial because slicing the mushrooms into thin pieces allows for faster and more effective drying. Use a sharp knife to slice the mushrooms as thinly as possible. Take your time and try to make the slices as uniform as you can. The ideal thickness will depend on the size of your mushrooms, but aim for slices that are no thicker than a few millimetres.
As you work, it's important to keep the mushrooms raw and uncooked. Cooking the mushrooms before drying will affect their ability to dry properly and may compromise their flavour. Raw matsutake mushrooms have a firm texture, making it easier to achieve thin, consistent slices.
Once you have your thinly sliced mushrooms, spread them out on a baking sheet or tray. Ensure they are in a single layer with adequate space between each slice. This arrangement allows air to circulate around each piece, promoting even drying. You can also place the mushroom slices directly on the racks of your oven or food dehydrator if they have small enough gaps to prevent the slices from falling through.
Thinly slicing your matsutake mushrooms is a crucial step in the drying process. Not only does it reduce the drying time, but it also ensures that the mushrooms will dry thoroughly and evenly. By following these steps, you'll be well on your way to preserving the delicate flavour and aroma of matsutake mushrooms for future culinary delights.

Use a low-temperature oven
Drying Matsutake mushrooms in a low-temperature oven is a great way to preserve their unique flavour and aroma. Matsutake mushrooms are a delicacy in Japanese cuisine, known for their distinct taste and smell, likened to a blend of pine, cinnamon, and spice.
To dry Matsutake mushrooms in a low-temperature oven, start by cleaning the mushrooms thoroughly but gently with a soft-bristled brush and cool running water. You can also use a mushroom brush to scrub away any dirt. Then, slice the mushrooms into pieces of similar size. Thinner slices, around 1/8" to 1/4" thick, are recommended for faster and more even drying. Next, spread the mushroom slices in a single layer on a parchment-lined baking sheet, ensuring none of the pieces overlap. Blot the mushrooms with a paper towel to remove any excess moisture before placing them in the oven.
Preheat your oven to a low temperature, ideally between 125°F and 150°F (52°C to 65°C). If your oven temperature goes below 140°F (60°C), you can prop the door open slightly with a heat-proof utensil to reduce the temperature and increase airflow. Place the baking sheet with the mushrooms in the oven and leave them for about an hour. Then, remove the mushrooms from the oven, and pat them dry with a paper towel. Turn the mushroom slices over and return them to the oven for another hour.
Repeat the process of removing, blotting, and turning the mushrooms over every hour until they are completely dry. The drying time can vary depending on the thickness of the slices and the humidity, but it typically takes 4 to 12 hours. Matsutake mushrooms are dry when they are hard, crisp, and brittle. They will continue to crisp as they cool, so let them cool completely before storing them.
Once the mushrooms are cool, transfer them to covered glass jars for storage. Label the jars with the variety and date, and store them away from direct light or heat. Properly dried Matsutake mushrooms can be stored for up to a year and can be rehydrated by soaking them in warm water for about 20 minutes before cooking.

Dehydrate for a long time
Drying Matsutake mushrooms involves a few simple steps, but it does require patience as the process can take a long time. Matsutake mushrooms, also known as pine mushrooms, are highly prized in Japanese cuisine for their unique flavour and aroma. They are a popular ingredient in high-end restaurants and among food enthusiasts.
To dry Matsutake mushrooms, you must first slice them thinly. This increases the surface area exposed to the air, allowing for a faster drying time. It is important to note that the mushrooms should be laid out in a single layer on a baking sheet. This ensures even drying and prevents the mushrooms from steaming or spoiling.
The next step is to place the baking sheet with the mushrooms in an oven set at a low temperature. This is a slow process, and the mushrooms should be left in the oven for several hours or until they are completely dry, hard, and crisp. An alternative to using an oven is to use a food dehydrator, which can be set to a specific temperature and left to dry the mushrooms over a more extended period.
The length of time required to fully dehydrate the mushrooms will depend on the thickness of the slices, the humidity of the environment, and the temperature setting of the oven or dehydrator. It is important to check on the mushrooms periodically to ensure they are drying properly and have not spoiled.
Once the mushrooms are completely dry, they will have a light tan to brown hue and a brittle, delicate texture. Properly dried Matsutake mushrooms can be stored and will retain their flavour and aroma for future use.

Freeze instead of dehydrate
While dehydrating matsutake mushrooms is a popular preservation method, freezing is another effective option. Freezing mushrooms can help retain their nutritional content and flavour while extending their shelf life. Here are some detailed steps to guide you through the process:
Preparing the Mushrooms
Start by cleaning your freshly harvested matsutake mushrooms. Use a damp towel to gently wipe away any dirt or debris. Avoid washing the mushrooms under running water, as they tend to absorb minimal water. Next, slice the mushrooms into pieces of uniform thickness. Aim for slices between 1/8 and 1/4 inch thick. Thicker slices will take longer to dry, so consider your time constraints.
Freezing Techniques
There are a few methods you can use to freeze your matsutake mushrooms:
- Freezing with a Baking Sheet: Spread the sliced mushrooms on a baking sheet in a single layer, ensuring they don't touch or overlap. Place the baking sheet in the freezer and leave until the mushrooms are frozen solid. Then, transfer the frozen mushrooms to a freezer-safe container or bag.
- Flash Freezing: This method is ideal if you want to freeze individual mushrooms or smaller portions. Place the sliced or whole mushrooms on a tray or plate and put them in the freezer. Once frozen, transfer them to a freezer-safe container or bag. This method makes it easy to grab the desired amount without thawing the entire batch.
- Blanching: Blanching is a technique that involves briefly boiling the mushrooms before freezing them. This process can help retain their texture, flavour, and colour. Boil a pot of water and prepare an ice bath. Add the mushrooms to the boiling water for about 30 seconds to 1 minute, then immediately plunge them into the ice bath to stop the cooking process. Drain the mushrooms and pat them dry before transferring them to freezer-safe containers or bags.
Storage and Thawing
Label your freezer-safe containers or bags with the date and content. Matsutake mushrooms can be stored in the freezer for several months. When you're ready to use them, simply take out the desired portion and thaw them at room temperature or in the refrigerator. You can also cook the frozen mushrooms directly in soups, stir-fries, or sauces without thawing, adjusting your cooking time accordingly.
Freezing matsutake mushrooms is a convenient alternative to dehydration, allowing you to preserve their flavour, texture, and nutritional benefits for future culinary creations.

Rehydrate in warm water
Dried matsutake mushrooms are a delicacy in Japanese cuisine, known for their unique flavour and aroma. They are also a good source of essential nutrients, including B vitamins, protein, copper, potassium, zinc, selenium, and dietary fibre.
To rehydrate dried matsutake mushrooms, start by placing them in a bowl of warm water. The mushrooms will need to soak for around 10 to 20 minutes. During this time, you may notice any debris or sand concentrating at the bottom of the bowl, while the mushrooms float above in clean water. After a few minutes, swish the mushrooms around in the bowl to ensure any remaining debris falls off.
Once the mushrooms have fully softened, gently lift them out of the water. You can then use a fine sieve or a coffee filter in a funnel to strain the mushroom water, which can later be added to stock or used in a sauce. Your rehydrated mushrooms are now ready to be cooked and used in a variety of dishes.
It is important to note that matsutake mushrooms are sensitive to overcooking or pairing with strongly flavoured ingredients, as this can cause them to lose their distinctive scent. Recommended cooking methods include baking, steaming, lightly frying, or simmering. They are commonly used in clear broth-based soups, ramen, hot pot, rice-based dishes, sauces, and omelettes.
