Blanching Mushrooms: Quick And Easy Steps For Perfect Results

Blanching mushrooms is an easy way to prepare them for freezing, and it can also enhance their flavour. To blanch mushrooms, you should first wash them and then slice, chop, cube or quarter them. Bring a pot of salted water to a boil, and then add the mushrooms. Leave them in the water for 2-3 minutes, or 10 seconds if they are shiitake mushrooms. Finally, drain the mushrooms and plunge them into a bowl of ice water to prevent overcooking. You can then freeze the mushrooms or cook them further as desired.

Cleaning mushrooms before blanching

• Select fresh, firm mushrooms with tightly closed caps. Avoid wrinkled, slimy, ragged, or spotted mushrooms.
• Wash each mushroom under running water to remove dirt. You can place them in a strainer and hold it under the tap, using your fingers to gently clean them.
• For lightly soiled mushrooms, you can use a damp paper towel or a soft mushroom brush to gently brush away any dirt. This helps prevent the mushrooms from absorbing too much water, which can affect their texture.
• After washing, trim the ends of the stems.
• Decide whether to blanch your mushrooms whole, sliced, chopped, cubed, or quartered. Smaller mushrooms like button mushrooms can be blanched whole, while larger varieties like portobellos are better sliced.
• If you want to maintain the colour of the mushrooms, soak them for 5 minutes in a lemon juice and water solution (1/2 teaspoon of lemon juice per cup of water).

Once your mushrooms are cleaned and prepared, you can proceed to the blanching process.

How long to blanch mushrooms

Blanching mushrooms is a great way to prepare them for freezing or for cooking them further. The blanching process for mushrooms involves placing them in boiling water for a short period, usually between 30 to 40 seconds to 1-2 minutes. This cooks the mushrooms partially, enhancing their flavour and texture while retaining their crunch.

To blanch mushrooms, first, wash the mushrooms under running water to remove any dirt. You can use a strainer to hold them under the tap and clean them with your fingers. Next, slice the mushrooms. You can chop, slice, cube, or quarter them, depending on their intended use. Thicker slices are great for snacks like pizzas, while thinner slices work well for sabzis or curries.

Once sliced, bring a pot of water to a boil. You can add a little salt to the water, as mushrooms absorb salt well during blanching. You can also add some vinegar to the water, if desired. Place the sliced mushrooms into the pot and allow them to cook for 30 to 40 seconds or up to 2 minutes.

After blanching, immediately transfer the mushrooms to a bowl of water to prevent "carry over" cooking, which ensures the mushrooms don't overcook. Drain the mushrooms using a strainer, and they are now ready to be used in your desired recipe or frozen for later use.

How to prevent overcooking

Blanching mushrooms is a great way to prevent overcooking and preserve their flavour, texture, and vitamin content. It is also a good way to prepare them for freezing. Here is a step-by-step guide to blanching mushrooms and preventing overcooking:

Step 1: Clean the Mushrooms

First, clean the mushrooms by washing them with water and removing any dirt or debris. You can also cut off the end of the stem and any oxidized parts. Soaking the mushrooms in water with lemon juice can help prevent discolouration.

Step 2: Prepare the Blanching Liquid

Fill a large pot with water and bring it to a rolling boil. You can also add a teaspoon of lemon juice or a little salt to the water, as mushrooms absorb salt well during blanching.

Step 3: Blanch the Mushrooms

Place the mushrooms in a steamer basket and put the basket over the boiling water. Make sure the basket does not touch the water. Cover the pot and steam-blanch for 3 minutes for sliced or button mushrooms and 5 minutes for whole mushrooms. Alternatively, you can add the mushrooms directly to the boiling water and blanch for 30 to 40 seconds.

Step 4: Prevent Overcooking

To prevent overcooking, immediately transfer the blanched mushrooms to a bowl of cold or ice water. This will stop the cooking process and prevent "carry over" cooking. Leave the mushrooms in the cold water for the same amount of time they were steamed.

Step 5: Drain and Use

Drain the mushrooms using a strainer and use them as required. You can also freeze blanched mushrooms for up to 12 months to preserve their flavour and texture.

By following these steps, you can successfully blanch mushrooms and prevent overcooking, ensuring they are partially cooked while retaining their crunch.

Freezing blanched mushrooms

Blanching mushrooms before freezing them is a great way to preserve their nutrition, flavour, and texture. Here is a detailed guide on how to blanch and freeze mushrooms:

Preparing the Mushrooms:

Before blanching, it is important to select fresh mushrooms that are intact and firm, with closed caps. Avoid mushrooms that are wrinkled, slimy, or discoloured. Clean the mushrooms by washing them under running water or by gently brushing or wiping them off. You can then slice, chop, cube, or quarter the mushrooms as per your requirement.

Blanching the Mushrooms:

To blanch the mushrooms, bring a pot of water to a boil. Add a teaspoon of lemon juice to the water to prevent discolouration. Place a steamer basket inside the pot and add the mushrooms. Let them steam for 2 to 5 minutes. Immediately 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 and helps retain their crunch.

Freezing the Mushrooms:

Once the mushrooms have been blanched and cooled, drain them and pat them dry. Spread the mushrooms on a tray and place them in the freezer until they are frozen solid. Then, transfer the frozen mushrooms into labelled resealable freezer bags or containers, removing as much air as possible to prevent freezer burn. Ensure you leave some headspace in the containers for expansion.

Storage and Usage:

Frozen mushrooms can be stored for up to 9-12 months, but it is recommended to use them within 3 months for best quality. When using frozen mushrooms, add them directly to dishes that will be thoroughly cooked, such as soups, casseroles, stews, or stir-fries. For dishes that do not require cooking, such as pasta, rice, or quinoa, thaw the mushrooms in the refrigerator overnight to soften before use.

Types of mushrooms to blanch

Blanching is a process used to stop the enzymes that cause vegetables to ripen, allowing them to be frozen and preserved for later use. Mushrooms can be blanched in a variety of ways, and the method often depends on the type of mushroom being prepared.

For example, when preparing fresh button mushrooms, it is important to select mushrooms that are intact and firm, with tightly closed caps. Wrinkled, slimy, ragged, spotted, discoloured, broken, or damaged mushrooms should be avoided. These mushrooms can be cleaned and blanched in boiling water for 30-40 seconds, or steamed for 3 minutes.

Chanterelle, honey, and cyclocybe aegerita mushrooms must be blanched in boiling water to reduce their viscosity. After blanching, these mushrooms can be cooked in olive oil, garlic, and parsley, or sautéed with butter.

Some sources suggest that steaming is a better method than blanching in water, as it preserves the flavour, texture, and vitamin quality of the mushrooms. However, steaming takes longer than water blanching, with sliced mushrooms requiring 3 minutes and whole mushrooms requiring 5 minutes.

Overall, while the blanching process may vary depending on the type of mushroom, the basic steps of cleaning, blanching, and cooling remain consistent.
