To freeze- These are best served fresh but can be frozen to eat later. To do this make the pretzel bites according to the instructions but do not salt them before baking. Once they are finished baking allow them to cool then place the tray in the freezer for about an hour. Remove the frozen bites from the tray and place in a freezer bag. Squeeze out as much air as possible. Wrap the bag in a layer of aluminum foil for another layer of protection. When ready to eat place bites on a microwave safe plate, sprinkle the pretzel bites lightly with water and sprinkle with salt. Wrap plate in a slightly damp paper towel and microwave for about 30-45 seconds (depending on your microwave)
