Measuring 300g of Bread Flour in the Kitchen
Because 1 US Customary Cup (236.6 mL) of bread flour weighs 127g when measured spooned & leveled, 300 Grams (300g) translates to 2.36 US cups (2 ⅓ cups + 1 ½ tsp). By contrast, using the scooped from bag measure (148g/cup — a 21g per-cup shift), 300g occupies 2 cups + 1 ¼ tsp (2.03 cups).
Without a kitchen scale, measure 2 ⅓ cups + 1 ½ tsp (37.8 tablespoons total) using spooned & leveled technique. Spoon into cup and level flat. Its 12-14% protein content yields dense granules that settle rapidly during storage.
