Here on our homestead, we try to reuse everything. The problem is, we love citrus and we can’t feed that to our chickens, our pigs won’t touch them, and they don’t compost well. While I do cook with citrus rind and occasionally have call to use it in teas I don’t have that many uses for it.
So it used to sit in large bags in our freezer until someone is coming for a visit. At which point, I would stuff some down the garbage disposal to make the house smell nice. That was all well and good except that folks don’t come out to the boonies for a visit that often. I started looking up other ways to use those darn peels.
