Brown sugar sitting in your pantry will eventually dry out and become clumpy. You can keep it baking-ready with nothing but an orange peel.
Just toss a piece or two of orange peel into an airtight container with the brown sugar. The peel stores moisture that will emanate throughout the container and keep the sugar fresh.
This could save you a trip to the supermarket the next time you need brown sugar for a recipe. If you have any extra orange peels when you're done, you could repurpose them into candles or a bottle of citrus cleaner.
