Everyone loves a caramel apple. I bet a caramel onion would not be so enjoyable.
Caramel apples are always popular around Halloween. It's easy to do, it's fun and people love it. But that doesn't mean you can't have a little fun now, right?
They sell caramel apple kits in stores. Just use the caramel wrap, heat it in the oven and you have a great prank treat!
Actually, the more I think about it, a cooked caramel onion, one that has say, carmelized from the heat, might be really tasty.
