How to measure cornstarch

Stir it to loosen it, spoon it into a dry measuring cup without pressing, and level the top with a straight edge. Scooping straight from the bag packs it down, so the cup weighs more than the table. For small amounts, dip the measuring spoon and level it the same way.

Other charts may list a different weight for a cup of cornstarch: it depends on how the cup is filled and on the brand. The numbers on this page come from one measured USDA portion (1 cup = 128 g), the same data the LevelSpoon converter uses, so the page and the app always agree.
