To make chocolate curls, soften a chocolate bar gently by microwaving only until the bar is slightly softer, but not melted. Using a vegetable peeler, go along the length of the bar and shave down in one long movement. The curl will fall off and once at room temperature again, can be picked up and sprinkled on top of the pie. Repeat until you have enough curls to garnish to your taste. Reserve any remaining chocolate for other applications.
