Slice the Mangos and place in the freezer until ready to use. Don't forget to include fruit around the stone.
Place the fruit in a food processor or blender. Add the maple syrup and blitz for 1 minute. Add the coconut milk and lemon juice, and briefly blitz to combine (a few seconds).
Serve the sorbet in bowls, or scoop into ice cream cones. (To make scooping easier, take the sorbet out of the freezer 10 to 15 minutes ahead of time).
Add any topping of your choice like fresh coconut, raw seeds, etc.
