To keep flour from being too dense when you measure it, food52 suggests two techniques: either scoop the flour with one measuring cup into another, then sweep the top with a knife, or whisk up the flour before scooping it up.
Turns out I've been guilty of measuring flour incorrectly all this time, just scooping without airing it out or making it lighter first. Check out the video above for a demonstration of the dump-and-sweep method and the scoop-and-sweep method.
