Put the frozen fruit in a food processor or blender. If you use a blender, you'll probably have to add some liquid - a bit of pineapple juice is delicious with the mango. Puree until the fruit is totally smooth and creamy - it takes a little while.

You can blend the coconut into the ice cream, or sprinkle it on top. This ice cream is best eaten right away - it will get quite hard if you refreeze it.
