01 - Combine the diced mango, grated ginger, lime juice, honey or agave syrup, and 1/2 cup cold water in a blender. Blend until completely smooth, ensuring all ingredients are fully incorporated.
02 - Pour the blended mixture through a fine mesh sieve into a pitcher or bowl, pressing with a spoon to extract the liquid while removing fibrous ginger and mango pulp.
03 - Fill two glasses with ice cubes, ensuring they are adequately chilled for serving.
04 - Divide the strained mango-ginger puree evenly between the prepared glasses, filling each approximately halfway.
05 - Top each glass with chilled sparkling water and stir gently to combine the puree with the sparkling water while maintaining carbonation.
06 - Garnish each glass with fresh mango slices, lime wedges, or mint sprigs as desired. Serve immediately while cold and sparkling.
