Pick out the freshest oranges in the pack. This is important because you don’t want to freeze bruised or old oranges. 

Wash and dry the oranges. Dry them as well as you possibly can. I recommend allowing them to sit out on the counter for about 30 minutes to be absolutely certain that they are dry.

Write todays date on your freezer bag. Tip: Write the date that they should be used by on the bag as well. This keeps you from having to do math later.

Place the oranges in a freezer bag.

Press as much of the air out of them as possible. 

Place the baggie in the freezer. Be careful not to stack things on top of the oranges before they have had time to freeze solid.
