Humidifier Stew

When our furnace was installed a few years ago, the furnace guys said it had a built in humidifier. Every year about this time, my skin gets so dry I wonder if they were pulling my leg. I've never gone down there for the purpose of verifying this. I don't know what I would look for. Instead, I make Humidifier Stew: One big pan of water, peelings from one or two oranges, clementines, or grapefruit, 2 cinnamon sticks. Combine and bring to a simmer on the stove. Add water as needed. (Do not eat.)

(Incidentally, our furnace guys are very trustworthy.)
