Remove the lemonade concentrate from the freezer and let it sit at room temperature for about 10–15 minutes, just until it softens enough to be stirred. It should still be slushy—not completely melted.

In a large punch bowl, beverage dispenser, or pitcher, add the slightly thawed concentrate and 4 cups of prepared lemonade. Stir well until fully combined.

Pour in 1 liter of Sprite (or your lemon-lime soda of choice) slowly. This keeps the carbonation from bubbling over and helps maintain the fizz in your punch.

Use a long spoon to give the mixture one final gentle stir—just enough to bring everything together without losing too much of the bubbly goodness.

Pour over ice if desired, and garnish with fresh lemon or lime slices for an extra pop of flavor and a pretty presentation.
