Measuring 100g of Gluten-Free 1-to-1 Baking Flour in the Kitchen

Because 1 US Customary Cup (236.6 mL) of gluten-free 1-to-1 baking flour weighs 148g when measured spooned & leveled, 100 Grams (100g) translates to 0.68 US cups (⅔ cup). By contrast, using the dip scooped measure (160g/cup — a 12g per-cup shift), 100g occupies ½ cup + 2 tbsp (0.63 cups).

Without a kitchen scale, measure ⅔ cup (10.81 tablespoons total) using spooned & leveled technique. Formulated with rice flour, starches, and xanthan gum. Spoon into cup and sweep level without packing down.
