What is the difference in dark brown and light brown sugar?
Also, can I substitute dark brown sugar for light brown?
Light brown sugar can be used in most recipes that require dark brown sugar. Similarly, dark brown sugar can be used as a substitute for light brown sugar if you add some refined white sugar to dilute the molasses flavor and color.
Also question is, which is better dark or light brown sugar?
Light brown sugar contains less molasses (about 3-1/2%) than dark brown (6-1/2%), accounting for differences in color and flavor. In general, if a recipe calls for brown sugar, it refers to light brown.
Not really. For the most part, dark and light brown sugars can be used interchangeably in recipes, as technically dark brown sugar simply has a slighter higher molasses content. However, more molasses does mean dark brown sugar has slightly higher levels of acidity and moisture.
