How simple are these!
Pre-heat oven to 160 C.
Grate parmesan cheese.
Place a baking sheet of paper onto an oven tray. Draw tea cup size circles on the paper. Turn paper over. Fill the circles with grated cheese. Place in oven until golden. Remove from tray with a spatula and place onto a cake rack to cool and harden. Keep in an air-tight container. You can place circles over a rolling pin to make crescent shapes.
