How to Section Fresh Fruit
To section fresh oranges or grapefruit, be sure to sharpen the paring knife first. A sharp knife is much safer to use than a dull one since it is less likely to slip while cutting. Cut a 1/2-inch-thick slice off both the top and bottom ends of the fruit. Cut the peel and white pith away from the fruit, using a downward cutting motion following the shape of the fruit. Place the peeled fruit piece on its side, then cut down along the membrane on both sides of each section to remove the fruit.
