I must confess that I am not much of a bread baker (I have to settle for drooling over all the beautiful items posted on this thread ) I pretty much only make yeasted doughs for holidays. I will say I have never noticed any problems But I am not sure if that is because yeast is less affected by altitude than chemical leaveners....or if it is because making dough is more of a “by feel” thing anyways... so you might just automatically adjust things like the amount of flour, rising time etc without really thinking much about it ...
I really didn't think I was but am having a good time figuring it all out and sure enjoy learning
