WARM a Baker's Chocolate square slightly by heating it, unwrapped, in the microwave for a few seconds until you can just smudge the chocolate with your thumb.
HOLD the square steadily between thumb and fingers of one hand and draw a peeler slowly over flat bottom of square. Allow a thin layer of chocolate to curl as it is peeled off the bottom of the square. This will make long, delicate curls.
MAKE short curls using the same technique on the narrow sides of the square. To arrange curls on a dessert, use a toothpick to lift them into place.
