Work with chilled coconut milk, coconut water and blueberries
In the bowl of a food processor, process 1.5 pints blueberries, coconut water, sugar and vanilla
Pour into a bowl and mix in the coconut milk and remaining blueberries. Add the vodka. Mix with a spoon. The mix is ready to process.
Cover and chill the mixture if you are not planning to process (it will hold well for up to a day in the fridge), otherwise, pour into the bowl of an ice cream maker and process according to manufacturer's instructions.
Store in the freezer in a covered bowl. The sorbet will remain "scoopable" with the addition of the vodka. If you skip the vodka, allow it to sit at room temperature for 5-10 minutes before serving.
