Making brown sugar

Recently, I started making a recipe of apple crisp only to find my cupboard bare of brown sugar.  I didn't have time to run out to the store, so instead I decided to try making my own.  After all, brown sugar is just regular sugar and molasses--both of which I had.  It ended up being so simple and it turned out great.  It took a bit of whisking until the molasses really spread throughout the sugar, so don't panic if you start out wondering whether the two will mix properly.

1 cup granulated sugar
1 scant Tbsp molasses

Whisk together until mixed well.
