In a medium saucepan, combine 4 cups of filtered water, 1 cup of fresh mint leaves, and 1 cup of organic cane sugar. Bring the mixture to a boil over medium-high heat, stirring constantly until the sugar dissolves, about 1-2 minutes. Once boiling, reduce heat and let it simmer for another 2-3 minutes, then remove from heat and allow to cool before straining out the mint.

In your blender, add the cooled mint syrup, 3 cups of fresh cubed watermelon, 1 chopped organic cucumber, and 1 tablespoon of freshly-squeezed lemon juice. Blend on medium-high speed for about 2-3 minutes until the mixture is smooth and frothy.

Pour the juice mixture through a fine-mesh strainer into a large pitcher to achieve a smoother texture.

Chill the strained juice in the refrigerator for about 1-2 hours or serve immediately over ice, garnished with fresh mint leaves and watermelon chunks.
