Measuring 75g of Cornstarch in the Kitchen

Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 75 Grams (75g) translates to 0.59 US cups (½ cup + 1 tbsp + 1 ¼ tsp). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 75g occupies ½ cup + ¾ tsp (0.52 cups).

Without a kitchen scale, measure ½ cup + 1 tbsp + 1 ¼ tsp (9.38 tablespoons total) using spooned & leveled technique. Cornstarch packs easily into a solid cake when pressed; scoop gently with a spoon and sweep level with a straightedge.
