In a blender, pulse ice until crushed and starts to resemble the texture of snow cone ice.
Add frozen mango chunks, lime, and mango smoothie. Blend until smooth (about 15-20 seconds).
Drizzle a ring of the chamoy sauce around the inside of a cup, then fill the cup with mangonada drink. Insert straw, top with diced mango, and finish it with Tajin fruit seasoning.
Recipe Notes
You can also coat the rim of the cup with chamoy sauce and Tajin in the same way you would with lime and salt for a margarita. Just make sure to do that step before adding the chamoy sauce inside the cup.
