Instructions
Blend blackberries with 1 cup of water in a food processor/blender & strain seeds through mesh strainer into a pitcher. Discard seeds. Add additional 1 cup of water, lime juice & sugar to the strained berries. Stir until sugar dissolves.
Just before serving, add chilled club soda slowly to prevent too much foaming. Stir lightly, if at all. Serve immediately.
