Why this varies

The single most variable ingredient in any recipe. Scooping straight from the bag compacts the flour and can yield 150 g or more; spooning it into the cup and levelling gives about 125 g. A 20% error in flour is the difference between a tender crumb and a brick — this is the ingredient most worth weighing.
