So, I picked up some dried shiitake last night. Original plan was to add ~2 oz at flame out. So I got home, pulled one out to sample for flavor and as i'm chewing on it I notice the package says "sulfites added". Being my first lager (schwatrzbier), I'm already a bit worried about underpitching, and adding sulfite to the wort doesn't seem like the best idea. On the other hand, it might be diluted enough to not make too big a difference.
Am I worrying too much? Would adding the mushrooms to secondary be better, or would that be worse since I'm bottle conditioning? I could always just go buy some fresh shiitake to use, but I've always found dried mushrooms give off more flavors.
