How Do You Know When Sugar Is Bad?
Sugar does not go bad in the sense that it becomes contaminated or harmful to consume. However, over time, sugar can become hard and clump together due to exposure to moisture or air. This can make it difficult to use or dissolve in recipes. To prevent this, keep sugar in an airtight container in a cool and dry place. If your sugar has become hard or clumped together, there are ways to soften it, such as placing it in a sealed bag with a slice of bread or microwaving it for a few seconds with a damp paper towel.
