Hi Bold Bakers!
As a professional chef with more than a decade of experience I want to get you into the kitchen and baking with confidence. I’m going to equip you with the skill you need to successfully bake anything you like.
Now, many times we see things and don’t know why they are the way they are. Clumps in brown sugar are a perfect example of this.
So many times I have had to break up hard lumps of brown sugar with my hands knowing that if it makes its way into my cake it will not work itself out It will just stay there in a big sugary lump.
Why Does Brown Sugar Clump?
So, brown sugar is a mixture of white sugar and molasses (treacle). It is made by rubbing the two together evenly turning the sugar brown. Watch my video on How to make Brown Sugar to see how.
The reason it clumps is due to the moisture in the molasses. Just think about it, white sugar is dry therefore doesn’t clump, but imagine mixing it with a wet ingredient and it will. There is extra moisture in brown sugar that white doesn’t have, therefore it clumps and goes hard.
How to Store Brown Sugar
If your brown sugar has turned clumpy or hard as a rock, there’s still hope! Follow my Bold Baking Basics tip and you will instantly remove clumps from your brown sugar.
Place a slice of bread or a marshmallow in the bottom of your brown sugar bag or container. This will absorb any extra moisture together leaving you with the perfect texture for measuring, baking and cooking!
What Does this Do?
The bread will soak up all the moisture in the container drawing it away from the sugar. The results are you end up with fine, clump-free sugar that is ready to be used.
Just note, the bread doesn’t go bad in the container. Because it drew all the moisture from the sugar it ends up drying out and getting hard, so it won’t spoil.
