This video shows you how to section an orange. For this you will need the following: an orange, a sharp knife, a bowl, and a pairing knife. To get started, cut off the top and the bottom of the orange with a really sharp knife. This will give you a flat surface. Cut away the hull of the orange with a pairing knife. Simply, work your way around the orange with your knife. Working over a bowl, make slits on each side of a wedge, at the cartilage, and scoop out each wedge. You can use this same technique with any other citrus fruit: e.g. grapefruit. Serve.
