Measuring molasses by cup and by weight
Molasses is thick and heavy, about 340 g per cup. Like honey, it clings to the measuring cup, so spray the cup with a little oil or measure by weight. Blackstrap molasses is stronger and more bitter than regular (light or dark) molasses and should not be swapped for it one-for-one in gingerbread, where the sweetness matters.
