OK, I'm certain not the approved
way, but I don't scrub mine at all anymore unless there's visible dirt
really visible dirt, which is very rare. I mean, they do go through several processes before they reach us. Baked or home fries I've noticed absolutely no difference. Nothing crunchy, nothing that has me take notice. I do remove any eyes though, usually with my thumbnail.
I do the same thing with mushrooms. I used to rinse them off under water and cut a thin slice of the stem off, then I heard that was bad for them and toughens them. I'll be danged if I'm going to wipe each individual mushroom off with a damp cloth
OK, maybe if I was eating one or two portabellas, but not a package of white mushrooms.
Absolutely no difference that I've noticed. And I often eat mushrooms "prepared" this way raw in a salad
Works for me. Your mileage may vary.
