Place the frozen fruit in a food processor and pulse until smooth.

Drape a sheet of cheesecloth over a mesh sieve and set it atop a bowl. Pour the fruit puree into sieve and gently press it through the cheesecloth and the sieve, into the bowl.

To serve, spoon a couple spoonfuls of fruit puree into a glass. Fill the glass the rest of the way with sparkling water. Stir and enjoy!
