Place a piece of waxed paper onto a flat surface. This helps to collect all the little pieces that will fly away and is much easier and less messy than trying to grate into a dish. You can use either a fine or a coarse grater depending on your preference. Coarsely grated chocolate is a nice decoration on cakes or desserts. Finely grated chocolate is a good stir in addition to cake batters or to garnish glazed or coated cookies or candies.
