1. Start by chilling your glasses in the fridge. This will keep your drink refreshing for longer and add a touch of elegance when serving.
2. In a large pitcher, combine the orange juice, cranberry juice, and lemon juice. Give it a gentle stir to blend the flavors together.
3. Add honey or agave syrup to taste. Stir again until the sweetener is fully dissolved. This is where you can channel your inner artist, tweaking the sweetness to your liking.
4. Just before serving, pour the chilled sparkling water into the juice mixture. Stir gently to preserve the bubbles.
5. Fill your chilled glasses with ice cubes, if using, then pour the sparkling drink over the ice.
6. Garnish each glass with a sprig of fresh mint. Not only does it look lovely, but it also adds a refreshing aroma as you sip.

Remember, the key to this drink is to balance the flavors, allowing each ingredient to shine without overpowering the others. Much like a Sunday roast, where each component complements the next.
