Clean porcini mushrooms with a brush or damp cloth
Cleaning porcini mushrooms is a crucial step before cooking them, as wild-foraged mushrooms can be very dirty, and even commercial mushrooms can have pathogens. Here is a detailed guide on how to clean porcini mushrooms with a brush or damp cloth:
Firstly, use a smooth, sharp knife or a paring knife to cut away any stringy or soil debris on the stump, removing the earthy part at the base of the stem. You can also use a knife to peel the entire outer skin of the mushroom. This initial step helps to loosen any stubborn dirt.
Next, use a brush to clean the mushroom. Take a firm, clean brush, such as a cheap toothbrush, and gently scrub the stem and the underside of the cap to remove any remaining dirt. You can also use a soft brush to avoid damaging the delicate mushroom surface.
Finally, if some parts are still dirty, use a damp cloth or paper towel to gently rub and wipe away any remaining dirt. Ensure that the cloth is only slightly damp, as porcini mushrooms are like sponges and will absorb water, affecting their flavour and texture.
After cleaning, you can cut the mushrooms depending on their size and your desired dish. For large mushrooms, separate the cap from the stem, slicing them into thin or thick pieces. Small mushrooms can be left whole and sliced lengthwise.
Remember, it is best to avoid rinsing porcini mushrooms thoroughly with water, but if the dirt is stubborn, a quick rinse under cold water is acceptable, followed by immediate drying.

Separate the cap from the stem
Before you start cutting porcini mushrooms, it is important to clean them thoroughly. Use a soft brush or a damp paper towel to remove dirt from the caps and stems. You can also use a knife to cut away any stringy or soil debris on the stem.
Once your mushrooms are clean, you can begin the process of separating the cap from the stem. Hold the cap of the mushroom with one hand and the stem with the other. Gently twist the stem to release it from the cap. Pull the stem out of the cap once it is loose.
Now that the stem has been removed, place the mushroom cap on a cutting board with the rounded side facing up. Use a sharp knife to cut the cap into thick or thin slices, depending on your preference and the requirements of your recipe.
If you are working with large porcini mushrooms, be aware that they may be riddled with tiny worms. Slice the mushrooms and inspect them for holes, which indicate the presence of worms. If the damage is minimal, you can cut out the affected sections and salvage the rest. Alternatively, you can prepare a saline solution of 2 tablespoons of salt to 1 litre of room temperature water. Cut the porcini into large, inch-thick pieces and soak them in the solution for three hours. The worms will evacuate the mushrooms, and you can skim them off the surface before disposing of them.

Cut the cap into thin or thick slices
To cut the cap of a porcini mushroom into thin or thick slices, start by cleaning the mushroom thoroughly. Use a soft brush or a damp paper towel to remove dirt from the cap and stem. You can also use a knife to cut away any stubborn debris on the stem. Once the mushroom is clean, hold it with the cap facing up on a cutting board. If the mushroom is large, it is advisable to separate the cap from the stem before slicing. Use a sharp knife to cut the cap into your desired thickness. You can cut the cap into thin slices for a more delicate presentation or thicker slices for a heartier texture. Be mindful that porcini mushrooms can vary in size and some may have slimy caps, so adjust your slicing technique accordingly. If you find any signs of worms or larvae, don't panic! Simply cut away the affected areas and salvage the rest of the mushroom. Remember to cook porcini mushrooms thoroughly before serving as they can be tough and difficult to digest when raw.
When slicing the cap, you can create thin or thick slices depending on your preference and the intended use. Thin slices are ideal for dishes where you want the mushrooms to cook quickly and integrate more subtly into the dish. Thicker slices, on the other hand, can be preferable for recipes that require heartier mushroom pieces or when you want the mushrooms to retain their shape and texture during cooking.
The thickness of your slices will also depend on the size of the mushroom cap. For larger porcini mushrooms, thicker slices can help maintain the integrity of the mushroom, while thinner slices may be preferable for smaller caps. Additionally, consider the cooking method you plan to use. If you're sautéing or stir-frying the mushrooms, thinner slices will cook more evenly and quickly. For grilling or roasting, thicker slices can create a more satisfying texture and flavor.
It's important to note that porcini mushrooms are known for their rich, nutty flavor and meaty texture. By cutting the cap into thin or thick slices, you can highlight these characteristics in your dishes. Thin slices may accentuate the nutty flavor, while thicker slices can provide a more substantial bite that mimics the texture of meat. Experiment with different thicknesses to find the perfect balance for your culinary creations.

Slice the stem crosswise or lengthwise
Before cutting porcini mushrooms, it is important to clean them thoroughly. Use a soft brush or a damp paper towel to remove dirt from the caps and stems. You can also use a knife to cut away any stubborn debris on the stem.
Once they are clean, you can begin cutting. If your porcini mushrooms are large, it is advisable to separate the cap from the stem. Place the cap on a cutting board with the rounded side facing up, and slice it into thin or thick slices, depending on your preference and intended use.
Now, let's focus on the stem. You can slice the stem crosswise or lengthwise. If you choose to slice it crosswise, cut the stem into thin or thick circles, depending on your desired thickness and intended use. You can add these circles to soups or stews, or use them as a tasty addition to other dishes. Finely chopping the crosswise slices is another option to consider, allowing you to incorporate the stem fully into your dish.
Alternatively, you can slice the stem lengthwise. This option is particularly suitable if you are working with small porcini mushrooms, as you can leave them whole and simply slice them lengthwise. However, you can also cut large mushroom stems lengthwise. This cutting method provides long, elegant strips of mushroom stem that can be used in various dishes.
In summary, slicing the stem of porcini mushrooms crosswise or lengthwise offers versatility in the kitchen. You can choose the cutting method that best suits your recipe and desired texture. Remember to clean the mushrooms thoroughly before cutting and always use a sharp knife to ensure precise and even slices. With these tips, you'll be slicing porcini mushroom stems like a pro!

Store raw porcini in the fridge for up to 2 days
Storing raw porcini mushrooms requires some care. Porcini mushrooms are a prized variety of edible mushrooms characterised by firm, white flesh and a thick, sturdy stem. They are typically expensive because they are foraged in the wild and are highly perishable. Therefore, it is important to store them correctly to avoid spoilage and waste.
Firstly, it is important to clean the mushrooms before storing them. Use a soft brush or a damp paper towel to gently remove any dirt or debris from the caps and stems. Avoid rinsing the mushrooms thoroughly with water, as they are spongy and will absorb it, affecting their flavour and texture. Mushrooms stored this way will become soggy and spoil quickly.
Once cleaned, wrap the mushrooms in paper towels to absorb any excess moisture. Then, place the wrapped mushrooms in a paper bag or a container with ventilation holes. This ensures the mushrooms can breathe and prevents the build-up of humidity, which can lead to the growth of worms and other unwanted visitors.
With proper storage, raw porcini mushrooms can be kept in the fridge for up to 2 days. However, it is always best to use them as soon as possible after purchasing to ensure optimal freshness and flavour. Check the mushrooms for any signs of spoilage before cooking, and avoid consuming them raw as it may cause stomach upset.
If you wish to store porcini mushrooms for longer, freezing is a good option. Clean and slice the mushrooms, then blanch them by boiling for 2-3 minutes before plunging them into an ice bath to stop the cooking process. Lay the mushroom slices on a baking sheet and freeze until solid. Finally, transfer the frozen mushrooms to airtight freezer bags, removing as much air as possible before sealing. Frozen porcini mushrooms can last up to 6-12 months in the freezer.
