01 - Rim the glasses with lime juice, then dip in coarse salt or sugar if desired for a decorative finish.
02 - Combine watermelon cubes, lime juice, orange juice, and agave syrup in a blender. Process until completely smooth and no fruit chunks remain.
03 - Pour the blended mixture through a fine mesh strainer into a pitcher to remove pulp, ensuring a silky smooth consistency. This step is optional but recommended.
04 - Fill prepared glasses with ice cubes. Pour the strained watermelon mixture evenly over the ice, dividing between the two servings.
05 - Decorate each glass with fresh lime wedges and watermelon slices. Serve immediately while chilled for the best flavor experience.
