Sparkling Mojito

1. In a sturdy glass, add the mint leaves, sugar, and 2 lime wedges. Gently mix to release the lime juice and mint oils.
2. Squeeze the juice from the remaining lime wedges into the glass, then drop them in.
3. Add the rum (if using) and fill the glass with ice.
4. Pour over chilled sparkling water until the glass is full.
5. Give everything a gentle stir. Garnish with a sprig of mint and a slice of lime.
6. Serve immediately and enjoy that fizzy, citrusy freshness!
