The pretzels are best warm from the oven however leftovers can be reheated. For the best results, use the oven vs the microwave. Preheat the oven to 350 degrees and wrap the pretzels in aluminum foil. Bake the pretzels for 5-7 minutes until warmed through. If you want to use the microwave, wrap the pretzel in a slightly damp paper towel and microwave until warm.
