To a food processor, add fresh mango and blend until a smooth puree forms.
Add 2 to 3 mint leaves into each cup along with a lemon wedge and lime wedge. Use a muddler to crush the juice out of the citrus fruits and release the flavors of the mint.
Then add about 1/4 cup of mango puree to each cup, adding less or more depending on your tastebuds.
Add about 1 to 2 tablespoons of simple syrup to each cup depending on how sweet you like it.
Fill the rest of the cup with ice and club soda.
Stir to mix all the flavors together and enjoy!
