Lobster mushrooms are large, white-capped mushrooms with a red fungus that gives them a taste and texture similar to lobster. They are parasitized by a fungus called Hypomyces lactifluorum, which turns them red and enhances their flavor and texture. Lobster mushrooms are prized for their tender meat and oceanic aroma, but they can be notoriously difficult to clean due to their irregular shape and the dirt and small life forms they often harbour. Here is a guide on how to effectively wash and prepare these unique mushrooms.

What You'll Learn

Use a brush, not a damp cloth
Lobster mushrooms are known to catch a lot of dirt in their cracks and concave caps, so cleaning them can be challenging. It is recommended to use a brush to wipe away the dirt, rather than a damp cloth, which can be messy and may remove the distinctive colouring.
A small brush can be used to lightly scrub the dirt from the cap, crevices and gills of the mushrooms before rinsing. It is important to scrub gently, applying enough pressure to remove the dirt without wearing down the red coating, which could lessen the flavour. If there is any excess dirt after brushing, the mushrooms can be briefly rinsed under cold water. Lobster mushrooms are quite sturdy, so if they are very dirty, they can handle a quick rinse in very cold water.
It is worth noting that using water to clean the mushrooms can affect their shelf life, so this method is best if you plan to consume a large quantity at once. Lobster mushrooms are also often filled with small life forms, such as bugs, larvae and snails, so it is important to inspect and clean them thoroughly before cooking.
To further ensure the removal of any unwanted guests, you can cut the mushrooms above the dirt line when harvesting and give them a few solid smacks against the ground or a tree to dislodge any remaining dirt, bugs or debris. Trimming any parts that are too dirty or embedded can also help ensure a clean mushroom.
By following these steps and using a brush instead of a damp cloth, you can effectively clean lobster mushrooms while preserving their unique colouring and texture.

Rinse with cold water, but don't soak
Lobster mushrooms are known to be tough to clean. They are often filled with small life forms and can collect a lot of dirt in their cracks and concave caps. Therefore, it is important to rinse them with cold water but not to soak them.
Firstly, cut the mushrooms above the dirt line and give them a few solid smacks against the ground or a tree to dislodge bugs, dirt, and sticks. Then, trim any parts that are too dirty or embedded. You can also use a brush to scrub away any remaining dirt before rinsing. Make sure to scrub gently so as not to wear down the distinctive red coating.
When rinsing with cold water, be sure to do so quickly and not to soak the mushrooms. Soaking will cause the mushrooms to lose their beautiful colouration and become waterlogged or mushy. It can also affect their shelf life. If you are using water to clean your mushrooms, it is best to eat or process a large quantity at once.
After rinsing, leave the mushrooms to dry in a strainer. Avoid rubbing them clean right after rinsing, as this can cause friction that wears down the red fungus. Instead, gently pat any wet areas with a paper towel before cooking.

Trim discoloured areas
Lobster mushrooms are notoriously difficult to clean because of their many folds, ridges, and deep centers that trap dirt, leaf litter, and debris. They are also often filled with small life forms like bugs, larvae, and slugs.
To clean lobster mushrooms, it is recommended to first trim the dirty ends and cut them above the dirt line. Then, give them a few solid smacks against the ground or a tree to dislodge any dirt and bugs.
Next, use a dry brush to wipe away the dirt. You can also use a soft-bristled brush like a pastry brush or clean toothbrush to remove surface debris. Be sure to check the entire cap surface and its crevices, as debris often hides in the folds.
Finally, trim any discoloured areas with a paring knife. Cut well around any brown spots or damaged areas and discard them. You can also use a knife to scrape away any embedded dirt or grit.
Lobster mushrooms should not be soaked or washed with a damp cloth, as this can remove their distinctive colouring and make them waterlogged or mushy. A quick rinse in very cold water is sufficient for particularly dirty mushrooms.

Tap to remove bugs and dirt
Lobster mushrooms are known to catch a lot of dirt in their cracks and concave caps, so cleaning them can be challenging. Here are some detailed tips to effectively tap and remove bugs and dirt from lobster mushrooms:
- Cut Above the Dirt Line: When harvesting lobster mushrooms, use a sharp knife to cut the mushrooms just above the dirt line. This ensures that you are not including any unnecessary dirt in the part of the mushroom you will consume.
- Solid Smacks: After cutting, give the mushroom a few solid smacks against a hard surface, such as the ground or a nearby tree. This impact will help dislodge bugs, dirt, and other debris that may be caught in the mushroom's crevices.
- Break into Sections: If necessary, break the mushroom into smaller sections. This will make it easier to access all the nooks and crannies and ensure thorough cleaning.
- Tap to Remove Debris: Hold the mushroom in one hand and give it several solid taps. Turn it upside down and tap the funnel-shaped base to dislodge any collected dirt, bugs, or debris.
- Use a Brush: To remove stubborn dirt or reach smaller crevices, use a small brush. Gently scrub the cap, crevices, and gills of the mushroom. Be careful not to scrub too hard, as you don't want to damage the delicate mushroom flesh.
- Rinse with Cold Water: If there is still stubborn dirt or debris, you can briefly rinse the mushroom under cold water. Focus the spray on any remaining dirty areas, and ensure the mushroom dries completely before cooking.
Remember, lobster mushrooms can harbour various insects and larvae, so it's important to be thorough when cleaning them. Additionally, always inspect the mushrooms for any brown spots or discolouration, trimming away any affected areas before proceeding with the cleaning process.

Dry before cooking
Lobster mushrooms are a challenge to clean due to their concave caps and cracks, which tend to collect dirt. While rinsing with cold water is an option, it is important to ensure that the mushrooms are completely dry before cooking. Leaving the mushrooms to air-dry in a strainer is a good idea, as this prevents any extra friction that might wear down the distinctive red coating. When you are about to start cooking, gently pat any remaining wet areas with a paper towel.
Lobster mushrooms are sturdy and can withstand a thorough cleaning. A hose with a spray nozzle set to "fan" or "line" can be used to direct a stream of water at medium to high pressure to blast away any debris. This method is especially useful if you have a large quantity of mushrooms, as it may affect their shelf life. If you only have a few mushrooms, you can simply rinse them in a sink with the highest pressure possible.
If you want to avoid using water, you can clean lobster mushrooms with a brush. Use a small brush to gently scrub the dirt from the cap, crevices, and gills of the mushrooms. Be careful not to scrub too hard, as you don't want to damage the red coating and reduce the flavour.
It is worth noting that lobster mushrooms may contain small life forms like bugs, larvae, and snails, so it is important to inspect them carefully and remove any unwanted guests before cooking. Using your hands to break apart the mushrooms, as suggested by some foragers, can help avoid accidentally harming any salamanders that may be hiding inside!
