Notes

Use ripe, chilled watermelon for the sweetest flavor.
Straining the watermelon is optional but creates a smoother drink.
Chill all ingredients before mixing for the most refreshing results.
Add the lemon-lime soda just before serving to maintain the bubbles.
Leftover watermelon puree can be frozen into ice cubes for future mocktails.
