What unique Kitchen/Cooking utensil is always in your TM

We got one of these as a gift and my wife and I immediately thought the same thing..."Oh great, another appliance to store.", but we fell in love with the thing. Used it so much at first we almost wore it out.
We used a few types of meat in it, but eventually settled on Canadian Bacon as the best. We found using filtered water helps reduce the "crud" buildup.
