The rolls should stay fresh for at least 2 days. However, if they do go stale you can freshen them in one of two ways. 1. Sprinkle the rolls with a few drops of water and place them in a hot oven for 5 minutes. 2. Wrap each stale roll in a sheet of damp kitchen paper towel and microwave on high for 10 seconds. You can also cut stale rolls in half, lengthwise, and toast in the toaster.
