01 - Combine diced mango, grated ginger, lime juice, honey (or agave), and 1/2 cup cold water in a blender. Blend until completely smooth, ensuring no chunks remain.
02 - Pour the blended mixture through a fine mesh sieve into a pitcher or bowl. Press with a spoon to extract all liquid while removing fibrous ginger and mango pulp.
03 - Fill two serving glasses with ice cubes, filling each about three-quarters full to chill the drink properly.
04 - Divide the strained mango-ginger puree evenly between the glasses, filling each about halfway to allow room for sparkling water.
05 - Top each glass with chilled sparkling water, pouring slowly to maintain carbonation. Gently stir once with a spoon to combine the layers.
06 - Add fresh mango slices, lime wedges, or mint sprigs as desired. Serve immediately while cold and bubbly for best flavor.
