Before I eat an orange, I use my box grater and shred the peel. I put the shredded peel on a paper plate and leave it on the kitchen counter a few days to dry. When the shredded peels are bone dry, they go into a Mason jar with a tight fitting cover. I then make a label for the jar. I use the dried peel in baking and canning recipes. I do the same with lemons, limes, tangerines, and grapefruits. The home-dried peels are much more flavorful than the stuff you buy and they are free.
