The kitchen utensil most likely to be lost in your kitchen, that is.
Mine is my vegetable peeler. It is blue (see picture) so you would think that it would be somewhat visible. I know it's not that large (fits in the palm of my hand) so maybe that's part of the problem. Considering too that it depends on the person putting dishes away as to where it might end up, I guess that's the reason that over 50% of the time that I want to use it, I have to track it down!
What is your "most wanted" kitchen utensil?
