Mushrooms are a delicious and versatile ingredient, but they can be pricey and have a short shelf life. One way to extend their life is to preserve them through blanching, steaming, or pickling. Alternatively, you can rehydrate dried mushrooms by soaking them in warm water or broth for at least 30 minutes. If you're feeling adventurous, you can even grow your own mushrooms at home using a grow kit or by propagating store-bought mushrooms. The process involves creating the right environment with moisture, temperature shifts, and a fruiting medium to encourage the growth of mycelium and, eventually, mushrooms. With some care and patience, you can bring mushrooms back to life and enjoy their unique flavour and texture.

Rehydrate dried mushrooms in warm water or broth for 30 minutes
Rehydrating dried mushrooms is an art. The process of rehydration brings them back to life and only requires a few simple steps. Firstly, soak the mushrooms in warm water or broth. Ensure that the mushrooms are completely submerged in the liquid. Leave them to soak for at least 30 minutes.
During the soaking process, the mushrooms will absorb the water or broth, causing them to become rehydrated and plump. This process not only restores their texture but also prepares them for cooking. Rehydrated mushrooms can be used in a variety of dishes, adding flavour and nutrition to your meals.
It is important to note that the type of liquid used for rehydration can impact the flavour of the mushrooms. Warm water provides a neutral base, allowing the mushrooms' natural flavour to shine through. On the other hand, broth adds a layer of flavour that can enhance the taste of the mushrooms in your dish.
The rehydration process is a simple yet effective way to revive dried mushrooms. By following these steps, you can easily incorporate these versatile fungi into your culinary creations, elevating your cooking with their unique taste and texture.

Bury the mushroom block in the garden to wick moisture from the soil
If you want to bring your mushroom block back to life, burying it in your garden is a great option. This method not only gives your mushroom block a new lease of life but also enriches the soil in your garden, promoting a healthier garden ecosystem.
To start, choose a shaded area in your garden that can maintain moisture. Direct sunlight can inhibit mushroom growth, so it's important to select a spot that receives ample shade throughout the day. Prepare the substrate by mixing it with materials like chopped straw, which will facilitate mycelium expansion. You can also apply solid-state fermentation processes to inoculate these substrates with edible mushrooms.
Once you've chosen the perfect spot, it's time to bury your mushroom block. Remove the block from its original container and place it in a hole, ensuring that it is completely covered. Adding a layer of mulch, soil, or wood chips on top will provide extra protection from direct sunlight and help with moisture retention.
With your mushroom block snug in its new home, all that's left to do is wait. Depending on the type of mushroom and environmental conditions, it may take a couple of weeks to a few months for new mushrooms to appear. During this time, it's important to maintain adequate moisture by watering the patch generously and ensuring it doesn't dry out.
While you wait for your mushrooms to fruit, you can rest easy knowing that you've contributed to a sustainable cycle. The buried mushroom block will decompose over time, releasing carbon dioxide. However, this carbon is not lost forever. The trees and plants in your garden will absorb this carbon dioxide and store it in their leaves, branches, and trunks. As the trees eventually decompose, they will release the stored carbon back into the soil, creating a cycle of carbon sequestration.

Grow mushrooms from store-bought stems using moist straw as bedding
Growing mushrooms from store-bought stems is a great way to propagate your own fungi at home. The process is quicker than growing from spores as you can use the mycelium already on the fungi. Here is a step-by-step guide to growing mushrooms from store-bought stems using moist straw as bedding:
Step 1: Prepare the straw
Firstly, you will need to buy some straw. You can purchase a large bale of straw from feed stores or local garden centres. You may need to chop the straw into smaller pieces, or you can pay the farmer to do this for you. Aim for pieces around 1-3 inches (2.54-7.62 cm) in length. Soak the straw in water for a couple of days to ensure it is moist enough. When you squeeze it, only a drop or two of water should come out.
Step 2: Prepare the container
You can use a cardboard box, paper bags, or a plastic bin to layer your medium. Place some of the moist straw at the bottom of your chosen container.
Step 3: Prepare the mushrooms
Choose oyster mushrooms or portobello mushrooms for the best results. Separate the ends from the tops and cut the ends into small pieces, around 1/4 inch (6mm) in size.
Step 4: Layer the container
Add a layer of straw pieces and then a layer of mushroom end pieces. Repeat this process until the container is full.
Step 5: Create the right environment
Keep the medium and mycelium damp and in the dark, with temperatures between 65-75 degrees Fahrenheit (18-23 degrees Celsius). Cover the container with a layer of plastic with holes poked in it to allow airflow.
Step 6: Harvest your mushrooms
After about two to four weeks, the mycelium should be ready to fruit. Cover the medium with plastic to preserve moisture and allow the fungi to grow. In about 19 days, you should be able to harvest your mushrooms.
It is important to note that mushrooms can be contaminated by mould or fungi spores, so make sure to follow strict protocols when handling the straw and container. Enjoy growing your own mushrooms at home!

Steam mushrooms for 3-5 minutes to preserve them
To preserve mushrooms, steaming is one of the best methods to prevent discolouration and retain their quality and flavour. Here is a step-by-step guide to steaming mushrooms for 3-5 minutes:
Firstly, clean the mushrooms by wiping off any visible debris with a damp cloth or a paper towel. Avoid washing the mushrooms, as this can shorten their shelf life. Then, slice the mushrooms into 1/4-inch pieces. If the mushrooms are larger than an inch across, cut them into quarters. For smaller mushrooms, you can steam them whole.
Next, place the mushrooms in a steamer basket above a pot of boiling water. Steam whole mushrooms for 5 minutes, and smaller slices and quarters for 3 minutes. After steaming, plunge the mushrooms into a bowl of ice water for the same amount of time they were steamed. This stops the cooking process.
Finally, strain as much water from the mushrooms as possible, then seal them in ziplock bags, removing as much excess air from the bag as you can. Store the mushrooms in the freezer, where they will last for up to a year.
You can also sauté the mushrooms in butter or oil for around 4 minutes, until they are almost fully cooked, and then preserve them in the same way.

Store mushrooms in a brown paper bag to extend their shelf life
Storing Mushrooms in a Brown Paper Bag
Mushrooms are delicate fungi with a perishable nature, so proper storage is essential to preserve their quality and extend their shelf life. One effective method is to store mushrooms in a brown paper bag, which can be found in grocery stores alongside the mushrooms.
Firstly, select undamaged mushrooms and place them into a clean, store-provided brown paper bag. Avoid sealing the bag, but loosely fold the top over to secure it. This simple step allows for proper air circulation, ensuring mushrooms stay fresh and appetizing.
The humble brown paper bag is an ingenious storage solution as it strikes the perfect balance between air circulation and moisture absorption. This prevents excess moisture buildup, preserving the delicate texture and taste of the mushrooms. In contrast, plastic produce bags trap moisture, creating a damp environment that degrades the quality of mushrooms over time.
By storing mushrooms in a brown paper bag, you can extend their shelf life. However, it is recommended to use the mushrooms within a week for peak freshness and flavor.
As an alternative to brown paper bags, wrapping mushrooms in paper towels and placing them in a bowl in the refrigerator can also help to absorb moisture and keep mushrooms fresh.
