Holly, I have one of these. You sit it right up on top of the stove. The meat you are cooking goes right on top of the top piece, which sits on the bottom piece, which sits on the stove. The heat goes through the first piece, into the second piece and right into the meat. Any juices that run off the meat goes into a trough, you can see them, on the first piece, and then that goes into the reservoir or mote on the outside of the first piece. Man oh man I make this sound complicated. However, think of it this way. You are standing in the rain with an umbrella, your child is underneath of you with their umbrella. The rain goes on your umbrella and falls off onto your childs umbrella and then goes to the ground. This is exactly the way the broiler works. I know it looks like the juices would go straight through, but they don't. The top piece simply covers the holes or slots. They are an interesting bird. If you still don't understand it, I'll ship you mine and you can look at it. In five seconds you could see what I mean. Sorry for the probable overkill.
