Plain (all-purpose) flour. White flour is made from hard and soft wheat grains after the outer coating of the grain is removed. It's then milled, refined, and bleached to whiten it to make it the superfine flour most commonly used in baking. Whole Wheat Flour. Whole wheat flour is made with the whole wheat kernel. Nothing is removed during the process, and you can visibly see the wheat bran present in the flour.
