Lightly chop dried cranberries. Pour orange liqueur over chopped cranberries and marinate overnight. Allow the cream cheese to soften to warm room temperature.
Chop the white chocolate into one inch (or smaller) chunks. In a glass bowl, microwave for 30 seconds only. Stir thoroughly. Microwave again for 20 seconds only. Stir thoroughly. Repeat if necessary at 10 seconds only, stirring very thoroughly each time, until only tiny chunks of chocolate remain. Continue stirring until the final chunks have melted from the latent heat in the chocolate.
Add the white chocolate to the cream cheese and whisk. Blend until smooth. Immediately add the cranberry mixture and blend thoroughly. The ganache will begin to firm as you blend; work quickly. Allow to stand at room temperature for two hours, or refrigerate for later use.
Spread crushed pistachios on baking sheet. Scoop the ganache mixture with melon baller or teaspoon; form into 1-inch balls and roll in crushed nuts until evenly covered.
Place nut-covered confections in paper or foil candy cups and store in airtight container in refrigerator. Serve on dessert platter at room temperature.
