Add cashew butter to bowl with cashew milk. Add salt and vanilla essence.
Blend well with immersion blender until fully combined.
Add blueberry jam to cashew mix and mix well with a spoon or immersion blender until fully combined.
Chill mix well, at least 3 hours or overnight if desired.
If using a self churning ice cream machine turn this on ten minutes before churning to allow bowl to chill, otherwise take churner bowl out of the freezer just before churning.
Churn ice cream. This took about 30mins in my machine but yours may vary.
When ice cream is done it will be soft serve consistency. Eat immediately or if a firmer texture is desired transfer to chilled container and freeze overnight.
To serve remove from freezer and leave for a few mins to soften up, then scoop and enjoy! Delicious with some extra blueberries on top or on its own
