Should I Measure Flour by Weight or Volume?

Most experts agree that dry ingredients like flour should be measured by weight rather than volume, especially in baking. The reason for this is that flours vary slightly in density, so a volume measurement will likely yield an incorrect amount of ingredient. Additionally, the amount that the flour is packed or compressed in the cup or tablespoon will alter the amount of ingredient being added.

For these reasons, a food scale is the preferred way to measure flour when cooking, rather than a cup or tablespoon.
