At the point the rolls are formed, placed in the pan and covered, they can also be refrigerated overnight. If rolls have been refrigerated overnight, the final proofing time will be closer to 1 1/2 hours. Storing Tips: Storing and serving rolls in one piece keeps them moist and soft. Store baked and completely cooled rolls in one piece in an air-tight plastic bag, or wrapped loosely in plastic wrap, then foil.
