Sprite Recipe

Combine sugar and citrus

In a small heatproof bowl or measuring cup, combine the granulated sugar, fresh lemon juice, fresh lime juice, lemon zest, and lime zest. Stir until the sugar begins to dissolve.

Warm to dissolve

Place the bowl in a saucepan with a little simmering water (double-boiler method) or microwave in 10-second bursts, stirring between bursts, just until the sugar fully dissolves and the mixture is smooth — about 20–30 seconds with microwave or 2–3 minutes with double-boiler. Do not overheat; you want a syrup-like consistency. If using citric acid, whisk it in now until dissolved.

Cool the syrup

Allow the citrus syrup to cool to room temperature (about 5–10 minutes). This prevents flattening the carbonation when combined.

Prepare glass

Fill a tall glass with ice cubes (about 1 cup). If serving multiple, divide ice among glasses.

Add syrup

Pour the cooled citrus syrup over the ice. Use all the syrup for one large serving or divide among 2 smaller servings (adjust quantity proportionally).

Top with carbonated water

Slowly pour 4 cups of cold carbonated water over the syrup and ice. Pour gently down the side of the glass to preserve fizz. Stir once gently with a long spoon to incorporate the syrup without losing too much carbonation.

Taste and adjust

Taste your homemade Sprite. If you prefer it sweeter, stir in an additional 1/2 to 1 teaspoon sugar (dissolve first in a small amount of warm water) or add a touch more fresh lemon or lime juice for brightness. If you want more tang, add a pinch more citric acid (dissolved).

Garnish and serve

Garnish with a lemon slice, lime slice, and a mint sprig if desired. Serve immediately while carbonated.
