There is no steam. Once you take the teakettle off the stove it stops steaming. When you put it in the freezer it just sits there and radiates heat into the ICE (which is the whole object of the exercise). My freezer has a metal bottom (part of the coils) so setting the teakettle there is not an issue, it just helps conduct the heat. I guess in a freezer with a plastic bottom you might want to use some "protection".
Anyway, it works for me. It's fast, easy, and I can do something else at the same time.
