Measuring 225g of Caster / Superfine Sugar in the Kitchen

Because 1 US Customary Cup (236.6 mL) of caster / superfine sugar weighs 225g when measured poured & leveled, 225 Grams (225g) translates to 1.00 US cups (1 cup). By contrast, using the spooned into cup measure (215g/cup — a 10g per-cup shift), 225g occupies 1 cup + 2 ¼ tsp (1.05 cups).

Without a kitchen scale, measure 1 cup (16 tablespoons total) using poured & leveled technique. Pour and level flat. Because the micro-granules pack closer together than regular granulated sugar, 1 cup weighs a dense 225 grams.
