I love the festive appearance of this candy. Although you can use a milk or dark chocolate, I prefer the way white chocolate offsets the red and green candies. If you want to use milk or dark chocolate, try substituting toffee bits for the crushed candies. When I make this, I use a product called "Red and Green Peppermint Crunch" made by CK Products. Your local candy supply shop may have this in stock.
1 lb. white chocolate
1 cup crushed red and green peppermint candies
Line a cookie sheet with wax paper or aluminum foil. Carefully melt the white chocolate in the top of a double boiler or in the microwave. Stir in the crushed candies. Pour mixture onto lined cookie sheet and spread into a thin layer. Place in refrigerator to cool. Break into small pieces to serve.
