A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Granulated sugars are levelled; brown sugar is packed firmly into the cup. Syrups are easiest to measure in a lightly oiled cup.
Also called: black treacle.
Weights are for a level US cup (236.6 ml) and level spoons, from USDA FoodData Central household measures. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of molasses weighs about 337 g (11.9 oz). A 250 ml metric cup weighs about 356 g.
1 level tablespoon of molasses is about 21 g, and 1 teaspoon is about 7 g.
100 g of molasses is about 0.3 cups, or 4.7 tablespoons.
A cup measures volume, not weight. Molasses is denser than water, so a cup weighs more (337 g vs 237 g).
