When I eat an orange, I usually try to zest it a little bit beforehand, and freeze the zest, so I will have some on-hand, when needed.
Well, here's another use for the skin of a fresh orange .... and this is just plain CLEVER! I 'stole' it from someone else, and sort of played with it 'til I got it right.
I made one today, and it has been burning for almost 10 hours already! Sheesh!
Scoop out all the orange fruit, scraping it away from the sides, leaving a thick wall of the white pith.
DO NOT CUT AWAY THE STEM IN THE MIDDLE. Leave it intact - this will be your candle wick!
Remove any scraggly ends of the stem "wick", and sort of form the "wick" into a nice straight, single piece.
Fill the orange half with oil [any type of cooking oil, canola oil, vegetable oil, etc.], almost to the top, but about 1/4" below the top of the stem "wick". Allow to sit for about 30 - 45 minutes, for the "wick" to absorb some of the oil.
Use a long-stemmed lighter, like a Bic Torch or similar, and continue to hold flame on the "wick" until it lights. It won't light immediately. This takes a little while, so you won't be able to light it with a regular match the first time.
After the "wick" has finally caught and burned, you will be able to blow it out and re-start it very easily. But that first time, it takes patience.
