How to Measure Cornstarch in Cups
Cornstarch is one of the most fine-grained ingredients in the kitchen and compacts very easily. For accurate measurement, sift or stir the cornstarch first to loosen it, then spoon into your measuring cup and level with a straight edge. A correctly measured cup weighs 128 grams.
Most recipes call for cornstarch in tablespoons, not cups. Use the calculator above to convert tablespoons to grams precisely — 1 tablespoon of cornstarch weighs 8 grams.
Pro tip: Always mix cornstarch with a cold liquid before adding to hot liquids. Adding it directly to hot liquid causes immediate clumping that cannot be reversed by stirring.
