Airtight Container: Store brown sugar in an airtight container to prevent moisture loss and keep it from hardening.
Add Moisture: Place a slice of bread, apple wedge, or a dampened paper towel in the container with brown sugar to maintain moisture.
Clay Discs or Terra Cotta Stones: Place a clay disc or terra cotta stone (available specifically for this purpose) in the container to keep brown sugar soft.
Freezer Bag: Transfer brown sugar into a resealable freezer bag, squeezing out excess air before sealing to prevent hardening.
