Old-fashioned Root Beer II

Measure out the granulated sugar and water according to your recipe ratio, typically 1 to 2 cups of sugar per quart of water for a simple syrup base.

Combine the sugar and half of the water in a medium saucepan over medium heat, stirring constantly until the sugar is completely dissolved.

Bring the sugar-water mixture to a gentle simmer, then remove from heat once the liquid is clear and all granules have dissolved.

Stir in the remaining water to dilute the syrup to the desired sweetness level and allow the mixture to cool to room temperature.

Transfer the cooled sweetened water to a clean pitcher or glass jar and refrigerate until thoroughly chilled.

Fill tall highball glasses with ice cubes, then pour the chilled sweetened base over the ice, filling each glass about halfway.

Top each glass with cold sparkling water or soda water, stirring gently to combine without losing carbonation.

Serve immediately in the tall glasses and enjoy the simple, refreshing old-fashioned root beer drink.
