Process the mango into a smooth puree.
Add gelatin powder into a small bowl and pour 3 tablespoons of cold coconut milk over it. Let it sit for 5–10 minutes, until it blooms into a thick paste.
In a saucepan add remaining coconut milk and sugar.
Heat gently over medium heat, stirring until the sugar dissolves. Do not boil.
Remove the pan from the heat. Add vanilla extract and salt.
Add the bloomed gelatin mixture.
Stir until fully dissolved and smooth.
Stir in the mango puree (at room temperature).
Mix until completely smooth and combined.
Grease ramekins with coconut oil or vegetable oil. Divide the mixture evenly into serving glasses or molds.
Refrigerate for at least 6 hours or overnight, until fully set.
Serve chilled.
If unmolding, dip the molds briefly in warm water and invert onto plates. Serve with fresh mango puree and decorate with berries, fresh mint and shredded coconut.
