Cornstarch Conversion: Cups to Grams
Cornstarch is a pure starch extracted from corn kernels, used primarily as a thickening agent for sauces, gravies, and puddings. In baking, it is added to cake flour substitutes and shortbread to reduce protein and create a more tender crumb. It thickens more efficiently than flour — use half the amount.
