Begin by cutting your chilled seedless watermelon into small chunks and adding about 4 cups to a blender. Blend on high for 30-45 seconds until the mixture is smooth and pureed.

Next, place a fine mesh strainer over a large bowl and pour the watermelon puree through it to leave the pulp behind.

In a large pitcher, whisk together cold water, freshly strained lemon juice, and granulated sugar until the sugar dissolves completely.

Slowly stir in the pureed watermelon juice into the pitcher with your lemonade base.

Fill glasses with ice cubes and pour the Watermelon Lemonade over the ice. Garnish with fresh mint.

Store any leftovers in a sealed container in the refrigerator for up to 3 days.
