Measuring 100g of Pure Maple Syrup in the Kitchen

Because 1 US Customary Cup (236.6 mL) of pure maple syrup weighs 312g when measured poured liquid, 100 Grams (100g) translates to 0.32 US cups (⅓ cup). By contrast, using the boiled down / maple cream measure (325g/cup — a 13g per-cup shift), 100g occupies ¼ cup + 2 ¾ tsp (0.31 cups).

Without a kitchen scale, measure ⅓ cup (5.13 tablespoons total) using poured liquid technique. Pour at eye level in a liquid measuring cup on a flat surface, or weigh in a bowl on a digital kitchen scale.
