Do I need to sift flour for quick breads?
quick breads are typically dense and do not require sifting, they also do not require kneeding. They are supposed to be quick and easy :) 

If the recipe calls for "3 cups of flour, sifted" then you would measure 3 cups of flour, and sift that. I have never seen a recipe call for "3 cups of sifted flour" but if it did you would have to sift, and then measure. Hope this helps.
