Prevent lumps in Granulated Sugar and keep Brown sugar from drying out.
The secret: Drop a few marshmallows in your sugar container. The Marshmallows will absorb any moisture and prevent lumps in granulated sugar.
Brown Sugar: Place Brown Sugar in a Ziploc bag. Drop a few mini-marshmallows in the bag. Then, squeeze out as much air as possible. Fold the bag around the sugar to make sure you've gotten the air out and store that way.
