Single-conversion pages for molasses
Working with molasses
Molasses sits in the sugars & syrups group, where the ingredient is denser than water, so a cup weighs more than 240 g and volume errors translate into large weight errors. Blackstrap molasses is slightly denser than light molasses. Warm the jar for a cleaner pour.
If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
