Oyster mushrooms, scientifically known as Pleurotus ostreatus, are a type of edible fungi and one of the most widely consumed mushrooms in the world. They are cultivated in many countries and are especially popular in Chinese, Japanese, and Korean cooking. Oyster mushrooms have a delicate texture and a mild, savory flavor. They are typically light grey or greyish-brown, but can also be found in other colors such as yellow and pink. When cooked, they have a smooth oyster-like texture and a slight hint of seafood flavor. While oyster mushrooms can be eaten raw, they have an unpleasant texture and flavor, so it is recommended to cook them before consumption. During the cooking process, oyster mushrooms release liquid, which can be encouraged by pressing them during cooking. This results in a meatier texture and a more concentrated flavor.

Oyster mushrooms release liquid when cooked
Oyster mushrooms are a type of edible fungi that are typically cooked before being consumed due to their unpleasant raw texture and flavour. They are commonly used in Chinese, Japanese, and Korean cuisine and are prized for their delicate texture and mild, savoury flavour. Oyster mushrooms can be cooked in a variety of ways, including sautéing, stir-frying, braising, roasting, frying, and grilling.
When cooking oyster mushrooms, it is important to avoid overcrowding the pan or skillet to prevent the mushrooms from becoming soggy and steaming instead of browning. This is because oyster mushrooms release moisture while cooking, and if they are too close together, the moisture will not be able to evaporate properly. To ensure proper evaporation, it is recommended to cook the mushrooms in batches, allowing the moisture to release and evaporate.
Additionally, pressing the mushrooms while cooking can help express the liquid, making them more tender and flavourful. A heavy lid, such as a cast iron skillet or a bacon press, can be placed directly on top of the mushrooms during cooking to facilitate this process. This technique is especially useful for pan-frying oyster mushrooms, as it draws out their liquids, concentrates their flavour, and gives them a meatier texture.
Furthermore, when cleaning oyster mushrooms, it is advisable to avoid rinsing them under running water as they absorb water quickly. Instead, a damp cloth or soft brush can be used to gently wipe away any dirt. If they are soaked in water for too long, they will absorb the moisture, which will then be released during cooking, potentially affecting the texture and flavour.
Overall, oyster mushrooms are a versatile ingredient that can be cooked in a variety of ways to enhance their flavour and texture. By understanding their tendency to release liquid during cooking, home cooks can employ various techniques, such as pressing and batch cooking, to ensure optimal results.

This liquid can be yellow
Oyster mushrooms are one of the most commonly cultivated types of mushroom in the world. They are prized for their delicate texture and mild, savoury flavour. Oyster mushrooms are typically light grey, greyish-brown, white, or tan, but they can also come in other colours, including yellow.
When growing oyster mushrooms, you may notice a yellow liquid in your grow kit bag. This liquid is a metabolite, a byproduct of the enzymes that the mushrooms secrete to digest their substrate. These enzymes act as an external stomach, breaking down the substrate externally. The yellow liquid can also help to fight off unwanted contaminants within the bag.
Oyster mushrooms can also release liquid when they are cooked. Pressing the mushrooms during cooking can help to draw out their liquids, which concentrates their flavour and gives them a meatier texture. If you are pan-frying oyster mushrooms, you can use a bacon press, a heavy flat lid, or a cast-iron skillet to press them down. Cooking oyster mushrooms uncovered on a medium to medium-low heat for around 10 minutes on each side will also help to release their liquid and give them a golden colour.
It is important to avoid overcrowding oyster mushrooms when cooking, as this can cause them to become soggy and steam rather than sauté. Leaving extra space allows the moisture to cook off, resulting in a true sauté rather than steaming.

Pressing mushrooms helps release liquid
Oyster mushrooms are a type of edible fungi and are one of the most widely consumed mushrooms in the world. They are typically eaten cooked, as they have an unpleasant texture and flavour when raw. Oyster mushrooms are versatile and can be cooked in a variety of ways, including frying, roasting, grilling, braising, sautéing, and stir-frying.
When cooking oyster mushrooms, it is important to leave enough space in the pan for moisture to cook off. If the mushrooms are crowded, they will become soggy and steam instead of browning properly. Pressing mushrooms during cooking is an effective technique to help release liquid and enhance their flavour and texture. By applying pressure with a heavy lid, skillet, or a specialised mushroom press, the mushrooms release moisture, resulting in a meatier and more tender texture. This technique also concentrates their flavour.
To achieve the best results when pan-frying oyster mushrooms, it is recommended to use a heavy lid, a cast iron skillet, or a bacon press to apply pressure on top of the mushrooms. If using a lighter lid, it can be weighed down with cans of beans. Pressing is optional, but it adds a unique flavour and texture to the dish. The mushrooms should be cooked on each side for about 10 minutes or until they turn golden and tender.
Additionally, when cooking oyster mushrooms, it is advisable to start with a higher heat to brown them and then lower the heat to allow them to soften without burning. Oyster mushrooms tend to shrink during cooking, so a pound of mushrooms will typically yield two larger servings or four very small servings. Proper storage is crucial, as oyster mushrooms are best cooked within a few days of purchase and remain fresh for up to five days.
