Follow these simple steps to create your refreshing Watermelon Mint Lemonade:

1. Prepare the Watermelon: Cut the watermelon into cubes. Remove any seeds if necessary.
2. Juicing Lemons: Roll the lemons on a flat surface to loosen the juice inside. Cut them in half and juice them until you have 1/2 cup of fresh lemon juice.
3. Blend Watermelon: In a blender, add the cubed watermelon. Blend until completely pureed to make a smooth watermelon juice.
4. Strain the Juice (Optional): For a smoother drink, strain the blended watermelon through a fine mesh sieve to remove pulp. This step is optional based on your texture preference.
5. Combine Ingredients: In a large pitcher, combine the watermelon juice, fresh lemon juice, simple syrup, and mint leaves.
6. Add Water: Pour in 1 to 2 cups of cold water, mixing well until everything is combined. You can adjust the water based on your taste preference for a stronger or lighter lemonade.
7. Chill: If desired, refrigerate the mixture for 20-30 minutes to enhance its refreshment level.
8. Serve Over Ice: Fill glasses with ice cubes and pour the watermelon mint lemonade over them.
9. Garnish: Add lemon slices and mint leaves on top for a beautiful presentation.

Prepare to enjoy a revitalizing drink that captures the essence of summer!
