Measuring 125g of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 125 Grams (125g) translates to 0.98 US cups (¾ cup + 3 tbsp + 2 tsp). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 125g occupies ¾ cup + 1 tbsp + 2 ½ tsp (0.86 cups).
Without a kitchen scale, measure ¾ cup + 3 tbsp + 2 tsp (15.63 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.
