2 cups sugar
1 cup hot water
2 cups fresh lemon juice
1-gallon cold water
1. In a 1 gallon container, place sugar and hot water, and stir until sugar dissolves. Add lemon juice and cold water to render 1 gallon. Stir until well mixed.
2. Fill the soda siphon with cold water. Screw on 1 CO2 soda charger and shake vigorously. To ensure the water is really fizzy, refrigerate for 1-2 hours.
