I recently received a cookbook with quite a few recipes for Muscovado Sugar what is it and where do I get it? - (5/15/01)

Muscovado sugar  (also called Barbados or moist sugar):  

Muscovado sugar, a British specialty brown sugar, is very dark brown and has a particularly strong molasses flavor. The crystals are slightly coarser and stickier in texture than "regular" brown sugar.

Light and Dark brown muscovado sugars contain molasses; the darker the color is, the more molasses and therefore the stronger the flavour. They are used in the same way as light and dark brown soft sugars.

Substitution: If you can’t get muscovado, use a good-quality dark brown sugar.
