In a medium saucepan, combine your chosen fruit juice, sugar, and alcohol. Stir until the sugar dissolves completely to create a flavorful base.

Sprinkle the sodium alginate into the juice mixture while whisking continuously.

In a separate bowl, mix the calcium chloride with water until dissolved.

Using a dropper or pipette, fill it with the juice mixture.

Carefully drop the juice mixture into the calcium bath.

Allow the boba to sit in the calcium bath for 2-3 minutes.

Using a strainer, remove the boba from the calcium bath and rinse them gently in cold water.

Serve the boba immediately in your favorite cocktails or sodas.
