Due to the fact that this technology almost seems too good to be true, a lot of people may wonder how exactly you are supposed to use one. For the record, an external heat source is not going to be required and they are not going to be battery-powered or require the power from an AC socket in your home. Oh yeah, and no hot water is going to be required, either. Instead, all you will need to do is place any meats that you want to be defrosted onto the surface of the tray.
However, you could say there is a bit of an art to the way you place the meat, though. It is simple as you really just want as much of the meat touching the surface as possible. This way, the heat transfer from the aluminum (or other metal) is maximized.
