Hardened sugar is a common kitchen frustration, but a simple household item can restore it to its soft, usable state. According to a viral Instagram video by Krishna Dunkley, a slice of bread placed in the sugar container overnight can soften brown sugar that has turned into a rock-hard mass.
The hack works because brown sugar hardens when moisture from its molasses content evaporates. Brown sugar is hygroscopic, meaning it draws moisture from the bread, rehydrating the sugar crystals. Within 8 to 24 hours, the sugar becomes scoopable again, while the bread slice turns hard and can be discarded.
However, this trick is only effective for brown sugar, not white. White sugar hardens due to absorbing excess moisture, so adding bread would worsen the problem. For white sugar, the best prevention is storing it in an airtight container immediately after purchase and avoiding introducing moisture, such as by dipping a wet teaspoon into the sugar.
Krishna Dunkley demonstrated the method with fruit bread containing currants, but any bread will work. The simple fix has gained attention as a way to reduce food waste and save money, as many households previously threw away hardened sugar blocks.
