I have nothing against sugar, but there are so many better ways to enjoy the sweet stuff. Granulated sugar, brown sugar, honey, maple syrup and molasses all provide better, richer tastes and more interesting textures than powdered sugar. Besides, given that diners who order pancakes or French toast are already planning to pour syrup over them, powdered sugar is superfluous.
In my view, the only reason to buy powdered sugar is to make cake frosting.
