Why Weigh Molasses in Grams?
When a recipe calls for ½ cups of molasses, using a kitchen scale to measure exactly 170 grams will give you far more consistent results than volume measurement alone. This is because molasses can be packed, sifted, or scooped differently each time, leading to weight variations of up to 20%.
How to Measure Molasses by Weight
Place your mixing bowl on a digital kitchen scale and press "tare" to zero it out. Then add molasses until the scale reads 170g. This method is faster than measuring cups and eliminates the guesswork entirely.
Also Known As
Molasses is sometimes referred to as blackstrap molasses, treacle. The same conversion of 340g per cup applies regardless of the name used.
