Servings 4 glasses

Ingredients
  

  • 8 cups seedless watermelon cubed (about half a medium watermelon)
  • 2-3 tablespoons fresh lime juice from approximately 2 limes
  • 1-2 tablespoons honey or agave nectar optional, depending on watermelon sweetness
  • 10 fresh mint leaves plus extra for garnish
  • Pinch of salt enhances watermelon flavor
  • Ice cubes for serving
  • Lime slices and watermelon wedges for garnish

Instructions
 

  • Prepare the watermelon by cutting it into 1-inch cubes, removing any black seeds if not using seedless. The smaller the cubes, the easier they’ll blend into smooth juice.
  • Add watermelon cubes to your blender along with the mint leaves and blend on high speed until completely smooth, about 30-45 seconds. Work in batches if needed to avoid overloading your blender.
  • Strain the mixture through a fine-mesh sieve into a pitcher, using the back of a spoon to gently press and extract all the juice while leaving behind any pulp. This step ensures a smoother texture.
  • Stir in the lime juice and taste test your cooler. Add honey or agave if needed, depending on the natural sweetness of your watermelon. Add a tiny pinch of salt to enhance the watermelon flavor.
  • Refrigerate for at least 30 minutes to chill thoroughly. The flavors will meld together and develop during this time.
  • Serve over ice in tall glasses, garnished with fresh mint leaves, lime slices, and small watermelon wedges for a picture-perfect presentation.

Notes

  • For the best flavor, use a perfectly ripe watermelon that feels heavy for its size and sounds hollow when tapped.
  • This cooler can be made up to 24 hours ahead and stored in an airtight container in the refrigerator—just stir well before serving.
  • For a slushy version, freeze the watermelon cubes before blending, reducing or eliminating the ice.
  • The optional pinch of salt doesn’t make the juice salty—it actually enhances the watermelon’s natural sweetness.
  • If you prefer a pulp-free drink, strain twice or use a nut milk bag for ultra-smooth results.
