Measuring 85g of Cornstarch in the Kitchen
Because 1 US Customary Cup (236.6 mL) of cornstarch weighs 128g when measured spooned & leveled, 85 Grams (85g) translates to 0.66 US cups (⅔ cup). By contrast, using the dip scooped measure (145g/cup — a 17g per-cup shift), 85g occupies ½ cup + 1 tbsp + 1 ¼ tsp (0.59 cups).
Without a kitchen scale, measure ⅔ cup (10.63 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.
