Chef Don't wash mushrooms

Comment: A friend of mine told me today that you are apparently not
supposed to wash mushrooms but instead use a mushroom scraper. Have you
heard anything about this? Would you happen to know the reason? Or is this
a total rumor?

Supposedly washing mushrooms waterlogs them. However, Alton Brown debunked that pretty thoroughly on Good Eats (IIRC, the mushrooms did hold a tiny bit of extra water, but the amount was so small that you would never notice it for an indivdual mushroom.) I looked for a cite, but I couldn't find a link to Altons experiment (I did find several people who mentioned it, but I don't count those as very reputable cites.)

You can find the transcript of the Good Eats episode where Alton Brown tested that here: http://www.goodeatsfanpage.com/Seaso...Transcript.htm

I find mushrooms just go slimy if you wash them, and you can't really dry them easily - it's easier just to knock off any bits of dirt with kitchen towel.

I used to peel them, which I quite enjoyed when they were hefty and peelable, but didn't work well for button mushrooms. Now I've decided it's worth paying extra for pre-peeled (and even pre-sliced) button mushrooms, which seem to keep better anyway. Shhh!

P.S. Tarquin, the dirt is poo!

Yes, but they feed the horses on Dettol, so it's sterile...

I was worried that this was something that really mattered, like if you washed your mushrooms, you would die of some strange poison that formed from mushroom contacting water. I was all like "Oh no! I just had mushrooms in dinner and I washed them! I've been washing them all along!".

But most of the time, I saute my mushrooms, so the extra water doesn't matter at all. Actually, I don't see how it matters that they absorb water if you're just going to cook them and suck the water out anyway.

I used to work at a major mushroom farm watering mushrooms. We used to spray them with chlorine to make them white which is a bit of a concern but I haven't noticed a difference between washed and unwashed. I have a tendency to wash or at least examine anything I buy that is packaged.

I agree with RichardW that washing them makes mushrooms all slimy. I wipe them with a teatowel if anything, but supermarket mushrooms are usually fairly clean. In fact the ones you pick out yourself are usually freer of poo (thank you Chloe!) than the pre-packed ones.

Mushrooms also go slimy if kept in a plastic bag - the shop usually supplies special paper bags to put your mushrooms in, but if they run out the only alternative is usually a little plastic one - so I do rinse them if they've been enclosed for too long.

The Co-op near me never seems to have the paper bags so I usually have to use plastic. (When they do have paper, I buy extra mushrooms to celebrate.) They do keep for a few days in the fridge before going slimy, as long as my fridge hasn't turned itself right down and frozen them as it sometimes does.

If you keep them too long in paper, they go all dry and shrivelled, but they're still usable for longer than if you keep them in plastic I think.

One of my beginner cookbooks said not to wash mushrooms because they absorbed the water. They do get a bit slimy after washing. So i guess it's a matter of preference. I prefer slime over poo.

I'll wash mushrooms, but never any sooner than right before I am going to use them. I've never experienced them getting slimy, though.

It might be just me then. I tend to take much longer than the average person just to be more certain that something is clean.

I always wash mushrooms too, and reading about chlorine and horse poo is enough reason to do so. They only go slimy after washing, if they are not used fairly quickly afterwards.

I wash my shrooms as a matter of course. Aside from making them a bit slippery to handle what's the issue? They're mosty water anyway and are usually heading for a liquid cooking medium at some point...

Chanterelles à la crème

Ingredients:
160g chanterelle mushies, cleaned
1/2 tsp sherry vinegar
2 shallots, sliced
2 tbsp mixed diced vegetables (leeks, celery, carrots, onions etc)
1 garlic clove, minced
1 bay leaf
60ml chicken stock
generous knob of butter
1 tbsp crème fraîche
1 tbsp whipped cream
fresh thyme leaves
fresh rosemary, finely chopped
fresh parsley, finely chopped
oil for frying
salt and black pepper, to taste

Method:

Fry the chanterelles in a little oil for a couple of minutes until just done then season with salt and pepper. Place in a sieve to drain, not forgetting to collect the juices.

In the original pan fry the sliced shallots and diced vegetables until browned then add the balsamic vinegar and chicken broth. Add the garlic and bring to a rapid boil. Reduce quickly, adding the shroom juice.

Reduce the heat and add the butter. Whisk to dissolve then take off the heat and add the crème fraîche and whipped cream, whisking in. Add the chopped herbs to taste, stir-in the mushies and serve on crunchy toast.

I'm pretty sure that most commercial mushroom growers don't use poo anymore. I was told I was a complete heathen for washing my mushrooms, but I still do it. I wash them right before cooking. I give them a bath of baking soda and water, rinse thoroughly, and put them in the pot. Instead of sauteing, I reduce the fat by simmering them in mushroom base. They turn out much plumper that way.
