Melt the chopped chocolate in a water bath until it reaches 115 degrees F, stirring until very smooth. Pour 2/3 of the chocolate on to a marble slab or work surface. With a metal spatula, work the chocolate by spreading it back and forth across the work surface for at least 3 minutes until it is thick and on the point of setting. With a scraper, quickly transfer the chocolate from the marble to the reserved chocolate. Reheat the chocolate in the water bath.
The chocolate needs to reach 84 degrees F before dipping. Using the candy dipping fork, dip some of the pretzels in the milk chocolate. Allow to dry on a piece of wax paper. Follow the same procedure with the candied oranges and lemons. Let the candy set in the refrigerator.
