What does 1 cup of raw sugar weigh?

Does black sugar exist?

I don't think so. Here is some definitions of the types of sugar. ; Brown sugar (light and dark) =Refined white sugar that is then mixed with molasses syrup to impart color and a molasses flavor. The more syrup used, the darker the color and stronger the flavor. ; Raw sugar = The residue left after sugarcane has been processed to remove molasses and refine sugar crystals. It is not the same as brown sugar, though the tastes are very similar. In the raw state, sugar may contain contaminants such as molds and fibers. ; Demerara sugar = A type of raw sugar from Guyana. Large golden crystals and slightly sticky. ; Muscovado or Barbados sugar = A type of raw sugar. Very dark brown and a particularly strong molasses flavor. Slightly coarser crystals and stickier texture than typical dark brown sugar. ; Turbinado sugar = A type of raw sugar that has been partially refined by steam-cleaning to remove the surface molasses and contaminates. Blond color with a mild molasses flavor. ; Free-flowing brown sugar = Specialty products produced by a special process that yields fine, powder-like brown sugar that is less moist than typical brown sugar, does not lump, and is free-flowing like granulated sugar. ; brown sugar (1 cup) ; ....... 1 cup white sugar + 2 Tbsp. sorghum molasses ; ; dark brown sugar (1 cup) ; .......1 cup light brown sugar + 1 Tbsp. molasses OR.......1 cup granulated sugar + 2 Tbsp. molasses ; ; light brown sugar (1 cup) ; .......2/3 cup dark brown sugar + 1/3 cup granulated sugar OR.......1 cup turbinado sugar ; ; demerara sugar ; .......turbinado sugar OR.......granulated sugar OR.......light brown sugar ; ; muscovado sugar.......dark brown sugar ; ; turbinado sugar ; .......demerara sugar OR.......light brown sugar OR.......raw sugar NOTE: Liquid or granulated brown sugars should never be substituted for regular brown sugar in recipes. NOTE: Unless otherwise stated by a particular recipe,brown sugar should correctly be measured by firmly packing it into a measuring cup of the correct size, using a spoon, spatula or other object to tightly press as much as possible into the cup and then level the top.
