I have several ways to make ice spheres at home, but the one that takes up the least amount of space is using a thermos and ice ball mold.
So I thought I would try using the ice ball press to smooth off the surfaces of ice balls made in the thermos method. It works only just okay - because the ice ball press makes larger spheres than the ice ball molds I have. They come out a little odd shaped as the fit is not perfect. A better size match would be better.
