Cultivated mushrooms: selection and preparation before cooking

Useful to know

For bought edible mushrooms, the university guide recommends a hard texture and avoid slimy or spotted specimens. Storage is refrigerated in the original packaging or paper bag. Rinsing is immediately before use. [1]

After cleaning, the slicing can comply with the dish. The source indicates slices for garnishing pizza and adding to an omelet. [1] For your own example, you can divide a purchase between these two uses by pre-determining the portions.

This is not a guide to collecting wild mushrooms. Neither the hardness, nor the color, nor the external propriety of a purchased product proves that an unknown mushroom is edible.

Evaluate the quantity against the cooking plan. The practical benefit of good storage is to keep the purchased product until it is used, not to extend the shelf life of mushrooms with already unwanted signs.
