the multiquick makes a pretty good sorbet. I don't think it would work for ice cream, but it was a successful experiment. :-)
I had 2 punnets of strawberries that were at the tail end of their usefulness--a few had already gone soft. I figured I had nothing to lose by whizzing them up, adding some sugar (if you do this yourself, add a little more sugar than you think you need [I used 4 Tb to a pound of strawberries--but taste before adding to see how sweet they are] as freezing decreases the perception of sweetness], and freezing it. I've made ice cream in a machine before, and I know the idea is to keep stirring the mixture as it freezes to keep the ice crystals small. obviously I couldn't do that, but a regular freezer won't work as quickly as an ice cream machine anyway, so I reckoned that if I gave it a beating every half hour or so, it would do the trick--and it did. It's not as fine as commercial sorbet, but it's pretty good, and I think proper sorbet recipes use sugar syrup anyway while I just used caster sugar. It's not perfectly solid yet, but it's about the same consistency as ice cream that's just come out of an insert-type machine, so I think I can leave it to ripen now. Not a bad way of salvaging something that would have otherwise gone in the bin. :-)
