I love mushrooms - they are yummy. Dh says they taste like slugs but I have never eaten a slug so I wouldn't know about that. He tolerates them "in" things, as the kids and I love them, but often fishes them out and leaves a small pile on the edge of his plate. Once, when I was mad at him, I made a chicken and mushroom pie with three kinds of mushroom in it.
Anyway, I wash my mushrooms - but I read you are not supposed to do this as it makes them soggy. You are supposed to wipe them. But that doesn't get them clean if they have bits of muck on them. I have met people who peel them. I think they are insane. To misquote Shirley Conran: "Life is too short to peel a mushroom."
My biggest bugbear about mushrooms is when they have marks in them from other peoples' fingernails. I guess this is inevitable when you buy loose mushrooms at the supermarket - people with long nails have not been careful when choosing theirs. I don't think it would be unreasonable to have two boxes of mushrooms with signs on "Mushrooms for people With Short Nails" and "Mushrooms for People with Long Nails." But it really annoys me when I buy pre-packed mushrooms and they have little crescent marks in them from peoples' fingernails. Now I'm sorry - but if you are a mushroom picker and packer by profession than it is incumbent upon you to ensure your nails are short. That's just common sense.
I also eat mushrooms raw - much to dh's horror. For a while pre-packed ones had a note on the box to the effect that they should be cooked before consumption but I ignored that. They haven't killed me yet.
In our last house I grew my own mushrooms in a polystyrene box. It was a kit I bought to grow your own mushrooms. This was very exciting for a city girl like me. They need to be grown in the cool and dark though and this house doesn't have a cellar so, sadly, I can no longer grow my own mushrooms but have to buy finger nail-marked ones from Tesco.
That's all I really want to say about mushrooms. Thanks for listening (well... reading).
