Back in the old days, as I recall, every recipe using flour said first to sift the flour. Now, as I look at pizza dough recipes and bread recipes, none of them instruct me to sift the flour. I still do sift it, probably out of habit. What effect does sifting the flour have on the finished product? Is there a reason why we don't tell people to sift first now? FYI, I am doing everything manually; no bread machine, no combination dishwasher/food mixer/car washer, no automatic food pulverizer. (I do have an electric garage door opener).
