For the Orange Layer
In a small bowl stir the 2 Tbsp of separate apple mango juice with the gelatin. Set aside and allow to bloom for 5 minutes.
In a small sauce pan add 1/2 cup of the remaining apple mango juice. Over medium low heat bring the mixture to just hot. You don't want it to boil but you want it too warm to stick your finger in for more than a second. Remove from heat once warm.
Add the bloomed gelatin to the warm juice and stir well until dissolved.
Add the remaining juice and stir to incorporate.
Pour on top of the set orange layer.
Add both ingredients to a jar and blend with an immersion blender until thick. Alternately you can use a blender.
