One cup, side by side
What does “spooned and levelled” mean for all-purpose flour?
King Arthur Baking states a method alongside the number: flour spooned into the cup and levelled off with a straight edge, not scooped straight out of the bag. That the chart bothers to say so is the point — 120 g is the weight of a cup filled that particular way, and a cup filled another way is a different weight. Weighing removes the question entirely, which is why the gram figure is the one worth keeping.
