1. Puree ingredients.
2. Place in ice cream maker and churn till nearly frozen.. stay near by and take a look at it a few times during the 15 min. Depending on the weather it could take shorter or longer..
This recipe is for instant eating. I haven't tried freezing it then serving it, it will probably be a solid doorstop the next day.
You can also do the same with tinned rasberries- just add more glucose, and try to strain out the pips.
