How to Make Chocolate Curls
Unwrap chocolate square, leaving chocolate on paper wrapper. Microwave on HIGH 10 sec. or just until you can smudge chocolate with your thumb. Hold chocolate square, bottom-side up, firmly between thumb and fingers of one hand. Slowly pull vegetable peeler over bottom of square with other hand, allowing a thin layer of chocolate to curl as it is peeled off the square. For shorter curls, pull vegetable peeler over one of the narrow sides of chocolate square. Refrigerate until ready to use. Use toothpick to pick up curls and arrange them on top of dessert as desired.
