A simple, refreshing sparkling watermelon lemonade with a tangy Tajín rim that balances sweetness, tartness, and spice for a perfect summer drink.

Ingredients

Scale
  • 4 cups fresh watermelon, cubed and deseeded
  • 1/2 cup fresh lemon juice (about 34 lemons)
  • 3 cups sparkling water (720 ml)
  • 2 tablespoons agave syrup or honey (optional)
  • 2 tablespoons Tajín seasoning
  • Pinch of coarse salt
  • Ice cubes
  • Optional: fresh mint or basil leaves for blending

Instructions

  1. Cut the watermelon into cubes, removing any seeds. Measure about 4 cups (around 600 grams). Chill if desired.
  2. Place the watermelon cubes in a blender and pulse until smooth, about 1-2 minutes.
  3. Optional: Strain the watermelon puree through a fine mesh sieve for a smoother texture.
  4. Juice 3-4 fresh lemons to get about 1/2 cup (120 ml) of lemon juice, removing seeds.
  5. Combine the watermelon juice, lemon juice, and agave syrup or honey (if using) in a large pitcher. Stir gently and taste to adjust sweetness.
  6. Chill the mixture for 30 minutes or add ice cubes directly to the pitcher.
  7. Mix 2 tablespoons of Tajín seasoning with a pinch of coarse salt on a small plate. Rub a lemon wedge around the rim of each glass, then dip the rims into the Tajín mixture to coat evenly.
  8. Just before serving, gently stir in 3 cups (720 ml) of chilled sparkling water.
  9. Pour the sparkling watermelon lemonade into the Tajín-rimmed glasses over ice.
  10. Garnish with a small wedge of watermelon, a lemon wheel, or a sprig of fresh mint. Serve immediately.

Notes

Use ripe watermelon for best sweetness. Straining the puree is optional but recommended for a smoother drink. Add sparkling water just before serving to keep fizz. Tajín rim adds a spicy, tangy contrast—adjust seasoning to taste. For a slushy variation, freeze watermelon cubes before blending. If Tajín is unavailable, substitute with chili powder and lime zest.
