Step 1
Peeling the oranges means that you remove the peel and the thin white membrane (pith) that protects the citrus fruit segments. With a knife, simply cut off both ends of the orange. Place the fruit on one of its flat bases, to remove the peel of citrus fruit flesh, slide the blade of a knife from top to bottom, then remove any excess pith.
Step 2
This technique is called "blanching" the skin, an important step to reduce the bitterness of most citrus.
