Finely chop 1 pound white chocolate. Microwave all but 1 cup in a microwave-safe bowl, stirring every 30 seconds, until melted, 2 to 3 minutes. Stir in the reserved 1 cup chocolate until melted. Spread on a foil-lined baking sheet until 1/4 inch thick; sprinkle with dried cranberries and chopped candied orange peel. Let set, about 1 hour, then break into pieces.
