So awkward, but come on it says right there on the package to wash those mushrooms or whatever it is… You’re not their mom but you don’t wanna eat feces or whatever ended up on the produce. A quick rinse is never going to be perfect but it’s better than nothing.
In the absence of legitimate suggestions, commiseration is welcome too 😉
This assumes you’re going to fry them. If you want raw mushrooms in a salad, it’s going to be a lot more noticeable.
Wash them whole and dry them right after. Contrary to popular belief, they don’t soak up water like sponges with a quick wash. You can easily prove this by just weighing them before and after washing/drying. The weight change is minuscule.
It doesn’t matter if they actually absorb water or not. Just try the mushrooms side by side, washed and unwashed. Decide based on what you prefer.
Total water absorption doesn’t matter that much because the significant thing is surface texture. If you’re going to dry them anyway you might as well instead wash them without directly pouring water on them.
A friend of mine solves this by meticulously peeling the caps and discarding the stems. It seems like a lot of work to me. I use a mushroom brush to get the dirt and substrate/manure off and call it good.
I’ve never had a problem with this, raw or cooked. The insides of my washed mushrooms are always dry.
Raw mushrooms are borderline wasteful to eat. We can’t digest the chitin and cell walls so most of the nutritional value passes straight through.
Just a note that raw mushrooms make people sick all the time and are a very common cause of his poisoning - especially wild mushrooms. You can get away with it with super common crimini mushrooms but some people are allergic even to that.
