01 - Combine diced mango, grated ginger, lime juice, honey or agave, and 1/2 cup cold water in a blender. Process until completely smooth and creamy.
02 - Pour mixture through a fine mesh sieve into a pitcher, pressing gently to extract liquid while removing fibrous ginger and mango pulp.
03 - Fill two serving glasses with ice cubes to chill thoroughly.
04 - Divide the strained mango-ginger puree evenly between glasses, filling each approximately halfway.
05 - Top each glass with chilled sparkling water and stir gently to combine flavors without losing carbonation.
06 - Decorate with fresh mango slices, lime wedges, or mint sprigs. Serve immediately while chilled and effervescent.
