STORAGE
Mushrooms can become slimy and develop brown spots within just a few days. Lots of theories seem to exist about the best way to store mushrooms: in a paper bag, wrapped in damp paper towels, in a sealed container.
Surprisingly, the best way to store mushrooms is in their original packaging. You just put the mushrooms directly in the fridge still in their wrapped container.
