In a small saucepan, combine the blueberries, water, allulose, and lemon juice. Stir over medium heat until the allulose has dissolved and the blueberries have burst and turned into a saucy consistency. This should take about 5 minutes. Allow to cool.
Pour the cooled blueberry mixture into a small blender and mix until all of the ingredients have been mixed together well. Once fully mixed, pour into a Ninja Creami container.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit.
Process the Ice Cream
After 24 hours, remove the Ninja Creami container from the freezer. If there is a large bump in the sorbet, melt or scrape the large bump so that the top is level.
Place the Ninja Creami container into the outer bowl of the Ninja Creami and then process on "SORBET."
If the sorbet is dry or crumbly looking (like sand), respin. You should not need to add any additional liquid during the respin. You may have to repeat this process a couple of times.
