Sprinkle the gelatin over ¼ cup of the coconut water. Whisk and let sit for 5 minutes.
In a saucepan, combine the remaining coconut water, coconut milk, and honey. Heat over medium, stirring until honey is dissolved and coconut milk is hot (not boiling).
Remove the saucepan from the heat. Whisk in bloomed gelatin and vanilla until smooth.
Pour the mixture through a fine-mesh sieve into a measuring cup.
If using fruit, arrange it in serving glasses. Carefully pour the coconut mixture over.
Refrigerate until completely set, at least 4-6 hours.
