everyone who has tried to store brown sugar knows that it doesn't last long before caking into a brick. this recipe is a solution for having instant brown sugar using ingredients that store well.
2 Tbsp. molasses
1 c. granulated sugar
add molasses to sugar and stir with a fork. store brown sugar in an airtight container to keep it soft.
for those who like to experiment, like me... try reviving your brick of brown sugar (or clumpy white sugar) by placing a soft piece of bread into the air tight container for a day or two. i've also tried this on dried up cookies and it worked.
