I know how to make ice cream. I have had much better success with salt and ice machines. I will be returning this product and spending $1100 on an Italian ice cream maker that had better work. If not, off it will go and I will spend $3500 for a commercial machine that will definitely work. Ice cream starts to melt just as it begins to freeze. There is not enough inertia in this "magic" bowl to either get proper overrun or phase change to ANY ice cream mix I have thrown its way. It also does not work on sorbet. It will make slushes and milkshakes, though, but isn't a blender a better way of doing that in less than 50 minutes?
