I've a question for the more experienced bakers here. Until yesterday's loaves I've been unsatisfied with my bread coming out with a crust that was overly thick and almost too hard. I just realized the only difference was this batch was made with Gold Medal Bread Flour vs. Bluebird Flour that I've been using all along. Can the flour make that much difference? I've just assumed flour is flour but it seems that's probably all wrong.
