Add all ingredients to a small saucepan, and bring to a boil. Let the sugar dissolve, and boil for one minute. Take off of the heat. Let steep for 10 minutes and strain out the solids.
Notes
The number of servings will vary depending on how sweet you like your sodas. Start by adding 1 tablespoon, and increase from there to see what you like. The batch makes about 1 & 1/2 cups, or 24 tablespoons worth.
