About measuring molasses

Molasses is the dark, bittersweet syrup left after sugar is refined, and it is very dense, so one US cup weighs about 337 grams. It is thick and slow to pour, so weighing straight into the bowl saves the frustration of coaxing it out of a measuring cup. Molasses brings both deep flavour and moisture to gingerbread, baked beans and dark cakes, so getting the amount right shapes both taste and texture.

Grease the cup or weigh molasses in the bowl. Its stickiness makes volume measuring messy.
