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 😉
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.
