Melt your chocolate gently in the microwave-70% works well. Best brands for this are Merckens or Classens disks. In a pinch, Wilton from Michaels will work. Once melted, dip pretzels and lay on wax paper. Add toppings and chill until set, just a few minutes! You can also melt ghirardelli dark chocolate chips for this but keep them chilled as they will melt on your hands faster than the disks!
