More ways to soften brown sugar after it has hardened:
- Place a fresh apple wedge in the bag of hardened sugar, seal the bag and leave it for 1 to 2 days until the sugar is soft again. Remove the apple wedge and stir sugar. Store in an airtight plastic bag.
- In a conventional oven, place the brown sugar in an ovenproof dish that has sides. Preheat oven to 225°F and place sugar in the oven for 5 or 10 minutes. Do not overcook, bake only long enough for sugar to soften. Cool and store in an airtight plastic bag.
To prevent brown sugar from becoming hard:
- Placing a piece of bread in with the brown sugar will prevent it from becoming hard.
- Sealing the package tight and storing it in the refrigerator to keep it soft and fresh.
