  1. Blender
  2. Knife and cutting board
  3. Measuring cups

Ingredients in This Recipe

  1. 4 cups watermelon cubes (seedless and ripe)
  2. 1/4 cup fresh lemon juice (about 2 lemons)
  3. 2 tablespoons honey or agave syrup (optional, for sweetness)
  4. 1 cup fresh mint leaves (roughly chopped)
  5. A pinch of coarse salt (for sprinkling)

Ingredient Spotlight

  • Watermelon: Provides natural sweetness and hydration
  • Lemon Juice: Adds tartness and a citrusy punch
  • Mint: Brings refreshing, aromatic flavor to the drink
  • Honey/Agave Syrup: Adds a touch of sweetness, balancing the tartness of the lemon

Ingredient Substitutions

  • Watermelon: You can substitute with other melons, like cantaloupe or honeydew, for a different flavor profile
  • Lemon Juice: Use lime juice for a tangier and sharper citrus kick. If you prefer a milder citrus flavor, lemon juice is recommended
  • Mint: You can use basil or cilantro for a unique twist
  • Honey/Agave Syrup: Use maple syrup as a more natural alternative. If using stevia, use a much smaller quantity (start with a few drops or a pinch) since it is much sweeter than honey or agave syrup

  2. Blend until smooth.
  3. Taste and adjust sweetness as needed by adding more honey or syrup.

  6. Garnish with additional fresh mint leaves or a small watermelon wedge.
  7. Serve immediately and enjoy!
