Orange SegmentsThis method also works for grapefruit. Cut the ends off a seedless orange just far enough to expose the flesh. Place orange cut end down and cut away the peel. Cut away as little of the peel as possible by following the orange's shape. Using a sharp knife cut along the inside of the membranes that separate the orange segments. Slice only down to the center of the orange. Continue around entire orange cutting out each section, leaving the membrane.
