It's pretty frustrating when you open up the canister of brown sugar and find that it's somehow become a huge, organic, solid lump. Sort of like a sandy rock, and totally impossible to use! I'm a big fan of a slice of bread stuck inside to keep the brown sugar nice and moist.
But, what can you do when the brown sugar is ALREADY completely hardened?
I put the canister (microwave safe) right into the microwave and microwaved on high for about a minute. I'd heard of this tip before, but had never tried it. It worked!! I could get out the brown sugar I needed. It's definitely the fastest way I've ever tried to soften brown sugar. Hope it helps!
