Time and time again, I’ve found myself in the same situation: reaching into the back of my fridge to find a forgotten package of mushrooms, slimy to the touch and absolutely not appetizing. Tossing them in the compost, background fading to the black-and-white of an infomercial, I shout: But I bought them less than a week ago! How! Why! There’s got to be a better way to store mushrooms.
