I've noticed at most of the latin or Mexican grocery stores that they sell 'pasilla chiles' that are in fact mislabelled ancho chiles, which are actually dried poblanos. I've read that this is fairly common in North America for some reason. It's my understanding that pasilla chiles (or dried chilacas) are still quite dark but fairly long and skinny, unlike the short/thick/wrinkly/dark ancho chiles that are commonly available and mislabelled as pasillas.
At the risk of sounding ungrateful, I'm not really looking for a list of latin markets in town that might have them (I'm familiar with most of these businesses). I would appreciate it however, if anyone has seen real dried pasillas in the flesh somewhere so I don't have to drive all over town!
Happy holidays folks!
