Born and raised in Michigan, I am proud of where I come from. Traverse City Michigan is The Cherry Capital. In July we have the Big Ole Cherry Festival for a week long festive Cherry Celebration. I buy the dried sweet cherries. Stock em up for Christmas treats or just when I want to dip em chocolate and have my own chocolate covered cherries.
Place semisweet chocolate & dark chips in microwave safe 8c. measuring cup or large bowl. In a microwave safe 2c. measuring cup or medium bowl. Heat semisweet chocolate,covered with wax paper on High 3 minutes or until almost melted,stir once. Remove and stir till smooth. Heat white chocolate on High 2 minutes stir once. Remove and stir until smooth.
Pulse nuts in food processor to chop. Add to Semisweet chocolate with the cherries. On a sprayed cookie sheet spread chocolate mixture to 1/4" thickness. Spoon dollops of white chocolate on and with a knife swirl to marble the chocolates. Sprinkle with remaining pistachios and cherries. (I chop the pistachios in processor to top the bark too)
Refrigerate bark 1 hour. Break bark into pieces. Store in airtight container in fridge up to a month. Pack in decorative plastic wrap or in decorative boxed with colored wax paper for gift giving.
