Put bananas and 1/2 cup coconut milk into a blender with your lime and vanilla powder. Blitz into a creamy smoothness.
Put the other 1/2 cup coconut milk into a saucepan, medium heat, and as it comes to the boil, switch off the heat. Sprinkle your gelatin over the coconut milk and whisk into it well, until you can’t see any anymore.
Add the thick banana coconut mix and combine all well. Then pour into little individual bowls, moulds or a simple serving dish for a big family presentation.
If you have a thermomix, you can do the whole process in the one thermomix bowl.
Let it set for 2-3 hours. You’re done.
