About cornstarch measurements
Cornstarch is a superfine powder that settles tightly in the box, giving a reference density around 0.51 g/ml (about 120 g per cup). It compacts under its own weight, so digging a cup from a fresh box packs in more than gently spooning it — fluff or sift it first for an honest measure.
