The popular taste of Sprite can be simulated with all natural ingredients you may already have in your kitchen. Balancing the sweet and sour flavors in a homemade Sprite will customize the beverage to suit your palette. Making fresh lemon-lime soda at home is less expensive than purchasing name brand soda at retail prices.
Heat the water in a small saucepan over medium heat until it nearly reaches a boil. This will only take a minute or two for this small amount of water.
Remove the saucepan from the heat and stir in the sugar with a wooden spoon until it is completely dissolved.
Pour the sugar syrup into a small glass or plastic dish and place the dish in the freezer for a 15 minutes. Setting a timer will help you remember the syrup and take it out before it freezes.
Juice the lemons and limes and pour the juice evenly into two pint glasses that are a little more than half full of ice. Pour the juice through a fine mesh stainer if you want to remove the pulp for a smoother beverage.
Divide the simple syrup and seltzer or soda water evenly between the two glasses until they are filled to within a quarter inch of the rim.
Stir the drink slowly with a long-handled spoon to combine the ingredients before tasting the drink. Adjust the sweetness level in the next batch of homemade Sprite drinks, to suit your personal taste, by adding more or less sugar to the drink.
