That's what happens I'm afraid Tenrec, proper ice cream will always be rock hard straight from the freezer, only option is to get it out 30 minutes before you're going to want to eat it :) It was glucose syrup I was thinking of as opposed to glycerin by the way, sorry. The problem you run into is that you start to move away from the simple/pure homemade ice cream if you try to alter what is essential a physical law, i.e. the freezing point of a milk/cream based liquid is about -0.5 degree C so coming out of even a freezer at -10 it's going to be very solid :(
