The Magic Behind Button Mushrooms

Button mushrooms, also known as Agaricus bisporus, are the youngest and smallest of the white mushrooms. They are the most popular mushroom variety, making up 90% of mushrooms consumed in the US. They are cultivated in over 70 countries and are one of the most widely consumed mushrooms globally. Button mushrooms are the immature form of edible fungi, which also include cremini and portobello mushrooms. They have a mild flavour, a delicate texture, and a high water content, making them versatile ingredients that can be cooked in a variety of ways.

Button mushrooms are the immature form of Agaricus bisporus

Button mushrooms, also known as white mushrooms, are the immature form of Agaricus bisporus. They are the youngest and generally smallest of the Agaricus bisporus mushrooms, which also include cremini and portobello mushrooms. All of these mushrooms are the same species at different stages of maturity. Button mushrooms are the least mature, followed by cremini mushrooms, and finally portobello mushrooms, which are the largest, darkest, and most mature stage of the species.

Agaricus bisporus is a basidiomycete mushroom native to grasslands in Eurasia and North America. It is cultivated in more than 70 countries and is one of the most commonly and widely consumed mushrooms in the world. Button mushrooms, in particular, are the most popular variety, making up 90% of the mushrooms consumed in the United States. They are also widely produced and consumed in India, Europe, and Australia.

Button mushrooms have a mild flavour and a delicate texture that intensifies when cooked. They are versatile and can be used in a wide range of recipes and cooking techniques, including tarts, omelettes, pasta, risotto, and pizza. They have a high water content, which dilutes their flavour and gives them a slightly squishy texture when undercooked. However, cooking them longer reduces their water content, resulting in a denser, meatier texture.

Growing button mushrooms is relatively easy and does not require sunlight, making it suitable for indoor gardening. They grow best in nitrogen-rich manure, such as horse manure. To create an indoor bed, a wooden box is filled with manure, and inoculated with mushroom spores. The bed is kept in a dark, damp, and warm environment, and after a few weeks, mycelium, or fine white webbing, begins to form, indicating the start of the mushroom colony. The bed is then covered with damp potting soil or peat, and the temperature is lowered. After about a month, the mushrooms are ready to be harvested.

They are cultivated in over 70 countries

Button mushrooms, also known as Agaricus bisporus, are cultivated in over 70 countries. They are the most popular mushroom variety, constituting 90% of the mushrooms consumed in the United States. They are also widely consumed in Europe, with Germany being the largest importer, and France and the UK being large producers and consumers.

The cultivation of button mushrooms began in the 16th century, but commercial cultivation started in Europe during the 17th century. The earliest scientific description of the commercial cultivation of A. bisporus was made by French botanist Joseph Pitton de Tournefort in 1707. The commercial development of the common white agaricus mushroom, however, began in 1925 when a white mushroom was discovered among brown mushrooms at the Keystone Mushroom Farm in Coatesville, Pennsylvania. Louis Ferdinand Lambert, a mycologist and owner of the farm, brought the white mushroom back to his laboratory. Similar to the commercial development of the navel orange and Red Delicious apple, cultures were grown from the mutant individuals.

Button mushrooms are cultivated in small, medium, and large farms across India, which exports the highest quantity of mushrooms to the United States. India's diverse agroclimate conditions and abundance of agricultural wastes make it an ideal environment for mushroom production. The Netherlands and China also account for 60% of mushroom exports, with China leading world production at 94%.

The process of cultivating button mushrooms involves preparing a substrate from plant wastes (such as cereal straw or sugarcane bagasse), salts, supplements, and water. To produce 1kg of mushrooms, approximately 220g of dry substrate materials are required. The substrate is then mixed with manure, typically nitrogen-rich horse manure, and placed in a wooden box. The inoculated material from the mushroom kit is spread on top of the soil and misted. The bed is kept in a dark, damp, and warm environment, and after a few weeks, white webbing or mycelium forms, indicating the start of the mushroom colony. The mycelium is then covered with damp potting soil or peat (called casing), and the temperature is lowered. After about a month, mushrooms start to appear, and they can be harvested by twisting them out of the soil.

Their substrate is made from plant waste, salts, supplements and water

Button mushrooms, also called white mushrooms or white button mushrooms, are the most popular mushroom variety, constituting 90% of mushroom consumption in the United States. They are also the cheapest variety and have the mildest flavour. They can be eaten raw or cooked in a variety of ways, including sautéing, stir-frying, grilling, braising, and roasting.

Button mushrooms are the immature form of the edible fungus Agaricus bisporus, which also includes cremini and portobello mushrooms. They are small, with a diameter of 1 to 3 inches, and have a delicate texture and a pale white colour.

The substrate on which button mushrooms are grown is made from plant waste, salts, supplements, and water. The plant waste used includes cereal straw and sugarcane bagasse. Urea, superphosphate, and gypsum are examples of salts added to the substrate, while supplements include rice bran and wheat bran.

To produce 1 kg of button mushrooms, 220 g of dry substrate materials are required. It is recommended that each ton of compost should contain 6.6 kg of nitrogen, 2.0 kg of phosphate, and 5.0 kg of potassium. The ratio of carbon to nitrogen in a good substrate should be between 25-30:1 at the time of staking and 16-17:1 for the final compost.

During the first phase of compost preparation, paddy straw is layered with water, fertilizers, wheat bran, and molasses. This mixture is then formed into a stack about 5 feet high and 5 feet wide. Button mushrooms thrive in nitrogen-rich manure, such as horse manure.

They have a delicate texture and mild flavour

Button mushrooms, also known as Agaricus bisporus, are the youngest and smallest of the white mushrooms. They are the least mature form of the edible fungus Agaricus bisporus, which also includes cremini and portobello mushrooms. All of these mushrooms are the same, simply at different stages of maturity.

Button mushrooms are characterised by their delicate texture and mild flavour. Their flavour is known as umami, a natural result of the glutamates present in the mushrooms. The mild flavour of button mushrooms intensifies when cooked, and they readily absorb the flavours they are cooked with. This makes them extremely versatile and perfect for a wide range of dishes. They can be eaten raw or cooked via sautéing, stir-frying, grilling, braising, and roasting.

The delicate texture of button mushrooms is evident in their ease of slicing and gentle handling requirements. Their flesh is somewhat fragile, and they bruise easily, turning pink and then brown when damaged. This feature also contributes to their delicate texture.

The high water content of button mushrooms, at around 92%, influences both their texture and flavour. The water content dilutes the umami flavour, resulting in a milder taste compared to more mature mushrooms. Additionally, undercooked button mushrooms may have a slightly squishy consistency due to their high water content. However, cooking them longer reduces their water content, giving them a denser and more meaty texture.

They are versatile and can be cooked in a variety of ways

Button mushrooms are the youngest and generally smallest of the white mushrooms. They are the least mature form of the edible fungus Agaricus bisporus, which also includes cremini and portobello mushrooms. Their versatility in cooking stems from their mild flavour, meaty texture, and ability to absorb the flavours they're cooked with.

Button mushrooms can be eaten raw or cooked via sautéing, stir-frying, grilling, braising, and roasting. They are easy to slice and prepare, but their flesh is delicate and they should be handled gently as they bruise easily. When bruised, the white flesh turns pink and then brown.

Button mushrooms can be used in a wide range of recipes, from tarts and omelets to pasta, risotto, and pizza. They can also be served as a side dish, sautéed with butter, herbs, and garlic, or as a topping for pizzas and burgers.

When selecting button mushrooms, they should be firm to the touch and have a uniform colour. They should be stored in a brown paper bag on the bottom shelf of the fridge, where they will last for at least a week. To clean them, gently wipe them with a damp cloth to remove any dirt from the surface, and trim the stalk. While some chefs recommend peeling mushrooms before cooking, this is not necessary with button mushrooms, as their skin is not tough.
