Summarize:

While the chocolate or chocolate mixture is still melting, stir in a few spoonfuls of peanut butter until the mixture is smooth again. This will add a delicious hint of peanut butter to your finished chocolate bars. Sprinkle a little finely ground sea salt over your chocolate bars immediately after pouring them into the molds. The salt will add a little more complexity to your bars, as well as enhancing the deliciously pure chocolate flavor. In a dry frying pan, lightly toast some peanuts, almonds, coconut, or whatever other types of nut you like. Scatter them over the bottom of your chocolate molds before pouring in your chocolate for an extra nutty crunch when biting in your finished chocolate bars. Finely cut up a few chunks of your dried fruit of choice and place one or two pieces into each chocolate mold. This will help balance out the richness of your chocolate, as well as adding a freshness to cut through some of the sweetness. Apricots, cherries, cranberries, or figs would all be excellent additions to your chocolate bars. Make sure not to use anything with a high water content, as this can cause your chocolate to seize and become unworkable.
Mix peanut butter into the melted chocolate for some subtle nuttiness. Add some sea salt for a sweet and salty taste. Mix in some toasted nuts for an extra crunch. Add some dried fruit to your chocolate for a tangy chew.
