How can brown sugar be stored to prevent hardening?
Brown sugar hardens when its moisture evaporates. Storing brown sugar in a way that allows the product to retain its natural moisture—in its original plastic bag (closed tightly) or in an airtight container—helps brown sugar stay moist. If brown sugar hardens, let it stand overnight in a sealed jar with a damp paper towel or apple slice. For a quick fix, heat the needed amount in a 250º F oven for a few minutes, or in a microwave oven on low for 1-2 minutes per cup. The softened brown sugar should be used immediately.
