Hey, hey, hey! Don't toss it at all even if you do buy a new one to bake cakes in. Use the old one for a vertical chicken roasting pan. It can be used in the oven or on the outdoor grill in place of a beer can. You'll catch the juices to make a sauce and it will also help to reduce flare-ups on the outside grill. When you use it in the kitchen, put it in another pan because some juices - not much - will "escape" through the tube opening.

This is real inspiration. Look what Julia became!
