Don’t expect an extremely creamy texture of this ice cream. Because blueberries contains lots of water itself, I don’t know how to reduce the icy texture when using blueberry as the main ingredient, except wiping the washed blueberry drier.
Re-challenged: Sept 4, 2016. The texture of the ice cream was improved A LOT, less slushy because I tried to reduce liquid contents. Still, may be I should replace maple syrup with just sugar to make it even better. Recipe below has been updated to reflect improvement.
