Chop chocolate and take in a glass bowl.
Coarsely chop pistachios.
Line a plate or a baking sheet with a parchment paper.
Take chocolate in a microwave safe bowl. If using a double boiler, check instructions below.
Microwave for 1 minute 15 seconds in 30 + 30 + 15 second intervals. Stir between each interval.
At this point, chocolate should be almost melted. If not microwave for another 15 or 30 seconds.
Keep stirring and let rest of the chocolate melt. At this point chocolate is warm enough to melt remaining unmelted chocolate.
Add ½ pistachios and cranberries to chocolate and mix well.
Pour melted chocolate on parchment paper lined plate or baking sheet and spread into a thin, ¼" layer.
Sprinkle remaining nuts and dry fruit on melted chocolate.
Let chocolate solidify. This will take 2-4 hours. Or you can refrigerate for some time.
Once set and firm, break chocolate into small pieces.
Store in an airtight container in a cool place or refrigerator.
