Make the Tropical Butterfly Refresher Base. Add the water, white grape juice, guava syrup, passionfruit syrup, and citric acid to a medium saucepan and heat over low heat. Whisk continuously until everything is dissolved. Set aside to cool.
In a small jar, stir together 3 tablespoon hot water and ⅛ teaspoon butterfly pea powder until dissolved, then set aside to cool.
Once everything is cooled to room temperature, add the popping boba to a tall glass. Add ice, then pour in ½ cup Tropical Butterfly Refresher Base and ½ cup water. Stir, then top with your prepared butterfly pea powder infusion. Drink up with a boba straw!
Notes
Note: This makes 2.5 cups of base, enough for 5 drinks. Store any leftover refresher base in the fridge for up to 1 week.
