What You'll Learn

Champignon is French for mushroom
Champignon is indeed French for mushroom. The word is borrowed from French into several other languages, including English, German, and Swedish. In English, "champignon" is sometimes used in fancy restaurants in the US, and in Australia. In the Deep South, Louisiana, and Alabama, the use of the term "champignon" for mushrooms may be a legacy of the region's French colonial past.
"Champignon" is used in the names of several varieties of mushroom, including "champignon de Paris", "Marasmius oreades" or "fairy ring champignon", and "Agaricus bisporus", which is also known as the cultivated mushroom. Agaricus bisporus is native to grasslands in Eurasia and North America and is cultivated in more than 70 countries. It is one of the most commonly and widely consumed mushrooms in the world. It has two colour states while immature – white and brown – and several names for its mature state, including chestnut, portobello, portabellini, button, and champignon de Paris.
Button mushrooms, which are white, are the most popular mushroom, representing about 90% of mushrooms consumed in the United States. They are widely available at supermarkets, grocery stores, and farmers' markets. They are easy to slice and don't require much pressure from a chef's knife. Their flesh is somewhat delicate, and they should be handled gently. They bruise easily, and when that happens, the white flesh turns first pink and then brown. They are great in pasta dishes, stir-fries, omelettes, salads, soups, sauces, as a topping for pizzas and burgers, and as a side dish, served sautéed with butter, herbs, and garlic, especially alongside grilled steaks and other meats.
Like other mushrooms, button mushrooms are prone to turning mouldy or slimy, so they should be used as soon as possible. However, storing them in the fridge for two to three days is fine, provided they are not encased in plastic, which traps moisture and can cause them to turn slimy. To preserve freshness, buy whole mushrooms and store them loose in the crisper drawer on the humid setting, with a clean paper towel underneath them.

Champignon mushrooms are best stored in the fridge
Champignon mushrooms, scientifically known as Agaricus bisporus, are native to grasslands in Eurasia and North America. They are cultivated in more than 70 countries and are one of the most commonly and widely consumed mushrooms in the world. They have two colour states while immature—white and brown—and are known by various names, including chestnut, portobello, portabellini, button and champignon de Paris.
Button mushrooms, for example, are already saturated with water—their water content is around 92%. If stored in plastic, they will sit in a damp container or bag, which causes discoloration, mould, and slime. Therefore, it is best to avoid storing whole mushrooms in plastic bags. Instead, buy whole mushrooms and store them loose in the fridge with a clean paper towel underneath.
If you buy pre-sliced mushrooms, remove any plastic wrap and store them in their container, uncovered, in the fridge. Sliced mushrooms should be used within three days, while whole mushrooms should be used within a week. If you are unable to use mushrooms within a week, consider freezing them. However, fresher mushrooms tend to freeze better, so do this sooner rather than later—and remember that you'll need to cook them first.
