Our mothers and grandmothers used a piece of bread or apple to try to solve the problem, but there was the possibility of mold imparting an undesired flavor to the sugar, and the solution was short lived.
Amazing ingenuity WTP can produce. Will begin searching for the terra cotta piece. Thus far, the apple slice seems to work; however, the brown sugar container is used often, depleted and replenished. Remember years ago brown sugar was needed and the only bag/box in our small country store was grabbed off the shelf. It could have been used to replace a broken brick on the house. Hard as a rock, it would have caused a concussion. Ice Pick?? about the only solution to a waste of time and money. Time for a Bed Bath and Beyond visit I suppose. Thanks for the info!!
