The week before last, we were responsible for bringing a healthy snack to Charlotte's preschool class. I sliced up a whole bag of navel oranges to go with the graham crackers I made. I had a huge pile of discards from the ends of the oranges. I put the ends into a pan of water, added a cinnamon stick, and let it simmer on low most of the morning. It smelled fantastic. I think I may try freezing our orange peels from now on so I can pop some in a pan whenever the house needs some freshening up.
