There are lots of tried and true methods to rescue dry and hardened brown sugar, but most of them require using other food like apple slices, bread or marshmallows to soften it. When I found my container of brown sugar all hard and stuck together this morning I really didn’t want to waste more food to save THIS food. So, I took the concept of adding moisture and decided to dampen a piece of paper towel. I just draped it over the edge of the sugar container and closed the lid. When I got back home this evening, the brown sugar was all softened, except for the very bottom portion. I stirred up the sugar and put in another towel. I’m sure it will ALL be soft by morning!
