How Can You Soften White Sugar That Has Turned Hard?


It is possible to soften white sugar that has turned hard by breaking it up into smaller pieces or blending it until smooth with a food processor or blender. Sugar hardens when it exposed to even small amounts of moisture.

The Sugar Association recommends breaking up hard sugar pieces with a heavy spoon or meat tenderizer before blending. Because sugar hardens when it is exposed to humidity, keep white sugar from getting hard by storing it in a sealed container. Other methods that work include rubbing the pieces over a fine cheese grater or using a coffee grinder, especially if only a small amount is needed. One sugar manufacturer recommends placing the hardened sugar in a casserole dish and cooking for 15 minutes in an oven pre-heated to 150-200 degrees. After 15 minutes, tap it with a spoon. If the sugar starts to fall off the chunks, place it back in the oven with the heat turned off for an hour. In humid climates, consider placing a piece of bread in the same container as white sugar. The bread absorbs the moisture, keeping the sugar from hardening. Sugar that is properly stored in an air-tight container has an indefinite shelf life.
