Ingredients

Makes 2 servings. Ingredient quantities update with the selected batch size.

  • 3 cups fresh watermelon, cubed and seeded
  • 1 oz fresh lime juice
  • 0.5 oz simple syrup (or more to taste)
  • 6 fresh mint leaves
  • 4 oz sparkling water
  • Ice cubes
  • Watermelon wedge, blueberries, and mint for garnish

Step-by-Step Instructions

  1. 1

    Prepare the glass

    Blend the watermelon cubes until completely smooth. Strain through a fine mesh strainer to remove pulp — you should have about 1.5 cups of deep pink-red juice.

  2. 2

    Build the drink

    In a shaker, muddle the mint leaves gently with the simple syrup.

  3. 3

    Add the finishing touch

    Add the watermelon juice and lime juice to the shaker with ice. Shake for 10 seconds.

  4. 4

    Garnish & serve

    Strain into two glasses filled with ice.

  5. 5

    Garnish & serve

    Top each glass with 2 oz of sparkling water and stir gently.

  6. 6

    Garnish & serve

    Garnish with a small watermelon wedge on the rim, a few blueberries on a pick, and a fresh mint sprig.

  7. 7

    Garnish & serve

    Serve immediately — fresh watermelon juice oxidizes quickly and is best within 30 minutes.

Recipe Tips

  • The juice should be deep pink-red. If it's pale, your watermelon wasn't ripe enough — choose a melon that's heavy for its size.
  • For a batch version: blend and strain the watermelon juice ahead of time, store in the fridge, and add sparkling water per glass when serving.
  • Add a pinch of Tajín or chili-lime salt to the rim for a spicy-sweet twist.

Make It Your Own

For a crowd: Prepare red and blue components separately. Set up a simple assembly line with clear cups, ice, and garnish so each guest gets a fresh patriotic pour.

Easy swaps: Use blueberries, blue raspberry, or butterfly pea for blue tones. Use strawberries, watermelon, grenadine, or cherry for red tones.

Frequently Asked Questions

How do I keep layers separate?

Use plenty of ice and pour the denser, sweeter components slowly over the back of a spoon.

Can I make this kid-friendly?
