Selecting mushrooms: choose fresh, firm, and bruise-free mushrooms
When selecting puffball mushrooms to freeze, it is important to choose fresh, firm, and bruise-free mushrooms. The best time to harvest these mushrooms is in the fall, so keep an eye out for them during this season. Freshness is key when it comes to preserving the quality of your frozen mushrooms.
Firstly, avoid pre-packaged containers. Instead, buy loose mushrooms so you can inspect their quality. Check the mushrooms from all sides and give them a gentle sniff; fresh mushrooms have a distinctive smell, so if something seems off, trust your nose. If a mushroom smells unpleasantly musty, it's best to avoid it.
Secondly, pay attention to the texture and appearance of the mushroom. The flesh should be firm, dry, and plump, with no slimy or blotchy patches. Smaller mushrooms are generally more enjoyable than larger ones of the same species. If the insides of the mushroom are snow-white, they are good to go. Signs of discoloration, such as a yellow, green, or brown hue, indicate degrading quality.
Lastly, different varieties of mushrooms have unique characteristics when fresh. For example, fresh chanterelles are white-yellow, gradually darkening as they age, while spoiled chanterelles are brown and soft. Champignons have a closed or half-open head, with light to medium brown lamellae, and both the cap and stalk feel dry and firm.
Once you've selected your fresh, firm, and bruise-free puffball mushrooms, it's time to prepare them for freezing. Blanching is a crucial step in preserving the flavor and texture of the mushrooms, followed by draining, freezing, and transferring to airtight containers for long-term storage.

Cleaning: wipe with a dry cloth, then a damp cloth to remove dirt
Puffball mushrooms are a forager's treat, with a soft and spongy interior and a mild, earthy flavour. They are highly versatile and can be grilled, fried, baked, sautéed, or used in soups, risottos, pizzas, and stir-fries. However, they have a heartbreakingly short shelf life, so freezing is an excellent option to preserve them for up to six months.
Before freezing puffball mushrooms, it is essential to clean them thoroughly to remove any dirt or debris. Here is a detailed guide on cleaning puffball mushrooms with a dry cloth and a damp cloth:
- Start by gently brushing off any visible dirt or debris from the surface of the mushroom using a soft brush or dry cloth. Be careful not to apply too much pressure to avoid damaging the mushroom.
- If you encounter stubborn dirt or stains, use a damp cloth to wipe the surface of the mushroom gently. Alternatively, you can briefly rinse the mushroom under cold running water, but be cautious as puffball mushrooms absorb water quickly and can become soggy.
- Once you have removed all the dirt, use a paper towel or clean cloth to pat the mushroom dry. Ensure no excess moisture remains, as it can accelerate spoilage during storage.
- After cleaning, inspect the mushroom for any signs of decay, discoloration, or insects. This step is crucial to ensure the mushroom is safe for consumption.
- If you find any discoloured or damaged areas, carefully trim them off with a sharp knife. Removing these parts will help ensure the mushroom stays fresh and extends its shelf life.
By following these steps, you can effectively clean puffball mushrooms with a dry cloth and a damp cloth, ensuring they are ready for freezing or cooking. Remember to handle the mushrooms gently and thoroughly dry them to maintain their quality and extend their shelf life.

Blanching: boil for 2 minutes, then submerge in ice water for 2 minutes
Blanching is a crucial step in the freezing process, as it helps preserve the flavour and texture of the mushrooms. To blanch your puffball mushrooms, start by bringing a large pot of water to a boil. Next, add your sliced mushrooms to the boiling water and let them cook for 2 minutes. After 2 minutes, remove the mushrooms from the boiling water with a slotted spoon and immediately submerge them in a bowl of ice water for 2 minutes. This will stop the cooking process and prevent the mushrooms from becoming mushy.
Once the mushrooms have been blanched and cooled, it’s time to drain them. Use a colander or strainer to remove as much excess water as possible. This step is important to prevent excess water from ending up in your freezer. Next, spread the mushrooms out on a baking sheet lined with parchment paper, ensuring they are spread out evenly and not touching each other. Place the baking sheet in the freezer and let the mushrooms freeze for at least 2 hours.
After the mushrooms have been frozen for at least 2 hours, transfer them to an airtight container or freezer bag. Be sure to label the container or bag with the date and contents, and place it in the freezer. Proper labelling will ensure you know what is in the container and when it was frozen. The mushrooms will keep for up to 6 months in the freezer. Freezing giant puffball mushrooms is a great way to preserve this rare and delicious ingredient for use throughout the year.

Draining and freezing: drain, spread on a tray, and freeze for 2 hours
Freezing is an effective method for preserving giant puffball mushrooms. To begin, clean the mushrooms and cut them into small pieces. Next, blanch the slices by submerging them in boiling water for two to three minutes. Immediately after, plunge the mushrooms into ice water for two to five minutes to halt the cooking process and prevent them from becoming mushy. Drain the blanched mushrooms in a colander or strainer, ensuring you remove as much excess water as possible.
Once drained, spread the slices in a single layer on a baking sheet lined with parchment paper. Ensure the mushroom slices are not touching each other and leave some space around each slice. Place the baking sheet in the freezer and let the mushrooms freeze for at least 2 hours. After this initial freezing period, transfer the frozen slices to an airtight container or freezer bag. Label the container or bag with the date and contents, and return it to the freezer. When properly frozen, giant puffball mushrooms can retain their flavour and texture for up to six months.
