The ice must be very well chilled, otherwise the result is not as nice.
We note but both - cold bowl and cold mass - then the pleasure is nothing in the way.
My results have always been great. Of course, not so much creamy as the Italians, but consistency can be quite impressive.
I can only recommend the device. For ice cream recipes and good suggestions I can ice for connoisseurs: 90 recommend seductive original recipes from Italy.
Have Fun!
