Yes, of course. All kinds of ice cream dishes that need to be stirred.
For the slush, the syrup (or the ingredients of your choice) is poured into the pre-frozen mixing container and the machine is started. The stirring time should be shorter than for normal ice cream, as a slush is not served completely frozen. The viewing window allows you to see the ice cream/slush/sorbet during the entire preparation process - so you can stop when the desired consistency has been reached
