Expiration & Storage Tips
When does powdered sugar expire?
Powdered sugar is a pantry stable ingredient, meaning it doesn't require refrigeration and can last quite a long time if properly stored. If unopened, it can last indefinitely. Once opened, when stored correctly it can maintain its best quality for about two years, but is still safe to use beyond that. As for homemade powdered sugar, generally, use same rule as traditional powdered sugar. As for freezing, it's not commonly recommended because it does not extend the shelf life. In addition, the moisture from defrosting could cause the sugar to clump together.
How do you tell if powdered sugar is bad?
Checking if powdered sugar has gone bad is relatively simple. Firstly, take a good look for any discoloration or growing spots which could indicate the presence of mold. You can also take a whiff; a foul or off smell can indicate spoilage. Lastly, taste it. If the sweetness has faded or if it tastes odd, it's time to toss it.
Tips for storing powdered sugar to extend shelf life
• Store powdered sugar in a cool, dry area, away from heat sources and moisture.
• Make sure to seal the container tightly after every use to protect it from humidity and pests. This helps prevent clumping and maintains freshness.
• If you're dealing with a large bag of powdered sugar, consider dividing it into smaller containers. This limits the sugar's exposure to air and contaminants each time you use it.
• If you detect any signs of spoilage, remember: when in doubt, throw it out. It's better to discard questionable sugar than to risk foodborne illness.
