For quick chocolate curls, pull a vegetable peeler along a chunky bar of milk chocolate. Milk chocolate is softer than semi-sweet or bittersweet chocolate. Lift the curls onto the dessert with a toothpick.
Make this pie early in the day so it has time to set up, plus you'll eliminate last-minute preparation. The chocolate curls can also be made ahead and refrigerated in a single layer in a small container.
Dark corn syrup has a caramel flavor and color, which gives it a darker color and stronger flavor. It works well with the chocolate in this pie.
