For a simpler Mango Dragonfruit Refresher Base: Instead of boiling the white grape juice and mango chunks together, combine 2 parts white grape juice (40 ounces) and 1 part mango juice (20 ounces) as your Mango Dragonfruit Refresher Base. Then combine the base with water/lemonade/coconut milk, frozen dragon fruit cubes, ice, and optional green coffee bean powder and shake to make your at home refreshers.
