Gently shake and tap the mold on your working surface to remove the air bubbles trapped in chocolate (trust me, there's nothing more annoying than air bubbles on your chocolates) then carefully top the chocolate tablets with your favorite toppings.
Allow the chocolate to crystallize properly before removing from the molds.
Notes
You can use any type of chocolate, from white to milk or dark or in between. Consider mixing various types of chocolates in one single bar, not only for taste, but also for the color contrast!
