Measuring 75g 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, 75 Grams (75g) translates to 0.33 US cups (⅓ cup). By contrast, using the spooned into cup measure (215g/cup — a 10g per-cup shift), 75g occupies ⅓ cup (0.35 cups).

Without a kitchen scale, measure ⅓ cup (5.33 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.
