When Should You Throw Out Brown Sugar?
Brown sugar has a long shelf life but can sometimes harden or develop lumps due to exposure to moisture. However, it doesn’t necessarily spoil or become unsafe to eat. If your brown sugar becomes too hard, you can try to soften it by placing a slice of bread or a damp cloth in the container for a few hours. If the sugar has been stored for a long time and has developed an off smell or taste, it’s best to discard it.
