The Ninja Creami Deluxe appliance requires the ingredients to be frozen before processing. It is not a typical ice cream machine with a compressor, but rather a powerful mixer that transforms frozen ingredients into ice cream, sorbet, gelato and other frozen treats.

You must therefore freeze the ingredients in the freezer for at least 24 hours before you can process them in the appliance. This ensures that the appliance's sharp blades can efficiently transform the frozen ingredients into a creamy consistency.
