After reading around a bit I saw that some brown sugar is made by the addition of molasses to refined white sugar.
Rather than keep various types of brown sugar I was wondering if all I needed was molasses and refined white sugar. I could then 'make' the particular brown sugar when needed. It would certainly be cheaper.
Any problems with this?
see quote from Wikipedia: Brown Sugar
Brown sugar is a sucrose sugar product with a distinctive brown colour due to the presence of molasses. It is either an unrefined or partially refined soft sugar consisting of sugar crystals with some residual molasses content, or it is produced by the addition of molasses to refined white sugar (so-called Molasses Sugar).
Brown sugar contains from 3.5% molasses (light brown sugar) to 6.5% molasses (dark brown sugar) based on total volume. Based on total weight, regular brown sugar contains up to 10% molasses.
