Add the mango and orange juice to a blender or food processor. Blend until fully liquid. Using a fine mesh strainer set over a medium pot, strain out the juice using a silicone spatula to push down the pulp. You should have about 1 1/3 cup of liquid.
Sprinkle the gelatin over the liquid and lightly mix. Allow to harden for 2-3 minutes.
Transfer the pot to the stove and heat over low heat for 3-4 minutes or until fully liquid.
Use a dropper to carefully transfer the liquid into a mold, filling about half of each cavity in the mold. Alternatively, you can use a large glass container, filling it half way.
Transfer to the fridge for about 2 hours or until fully set.
For the matcha layer
Add the warm water to a small bowl and sift the matcha powder over the water. Whisk well with a matcha whisk, or a milk frother.
Pour the coconut milk into a pot and add the matcha and honey. Stir well before sprinkling the gelatin over the liquid. Lightly mix and llow to harden for 2-3 minutes.
Transfer the pot to the stove and heat over low heat for 3-4 minutes or until fully liquid.
Use a dropper to carefully transfer the liquid into a mold over the mango layer, fully filling the mold.
Return to the fridge for another 2-4 hours or until fully set.
Carefully remove from the mold and keep chilled for 2-3 days.
