The best method for dipping pretzel rods is to use a tall glass or jar that is tall enough to insert the pretzel rod. This method is the easiest way to get full coverage without having to use a spoon or spatula. Once the pretzel rod is inserted into the cup, spin the rod and lift so that any excess chocolate drips back into the cup. To avoid a flat side on the pretzel, remove as much excess chocolate as possible so that when the pretzel rod is laid flat it helps to avoid pooling as you let the chocolate set.
