Does Powdered Sugar Go Bad? The answer is......................
Ever wondered if that powdered sugar that has been sitting on the shelf for nearly a decade has gone bad? Powdered sugar is not a standard ingredient used everyday, so it is important to ask yourself if it does and will go bad if left for years.
The answer is not as simple as yes or no. While it may not go bad, it can get stale and lose its integrity and taste. Powdered sugar is made from granulated sugar and a dash of cornstarch. Both of these ingredients can be kept for long periods of time, however, they can grow stale if stored improperly.
If powdered sugar is stored properly it can be kept for years without growing stale, however, the best rule of thumb in cooking with powdered sugar is to make sure a fresh batch is exchanged once a year. Many change out their powdered sugar during the holidays to ensure the taste is viable and the sugar has not turned stale.
To keep the powdered sugar at its best for months, store it in an air tight container or pouch. A glass jar with an air tight lid is the best way to keep the sugar fresh for a long period of time. It is important to keep moisture out of the jar so that it doesn’t get stale.
