Mango Dragonfruit Refresher 🍹

In a saucepan over medium-high heat, combine the red dragonfruit pieces, dragonfruit powder (if using), sugar, and water. Stir and bring to a boil.
Reduce the heat and let the mixture simmer for 10 minutes to soften the dragonfruit.
Mash the softened dragonfruit and strain the liquid through a fine mesh sieve to obtain dragonfruit syrup.
In a tall glass, place the freeze-dried dragonfruit pieces and fill with ice.
Pour in the grape juice, mango juice, and prepared dragonfruit syrup, stirring everything together.
