I've used this for quite some time and it always amazes me how the brown sugar pulls the moisture from the bread causing it to stay..........
Soft and Crumbly!
The bread doesn't fair so well. It'll be as hard as a rock later but that's ok! This lasts a long time. I only change mine out if the sugar starts to harden again, or if I happen to be making a sweet potato with butter, brown sugar and cinnamon.
Yum! I think that sugar deserves a new piece of bread!
