Begin by preparing a large pitcher. Pour in the elderflower syrup, followed by the freshly squeezed orange juice and lemon juice. Use a wooden spoon to stir the mixture well until the flavors are harmoniously blended.
Add the lemon zest to the pitcher, which will infuse an extra layer of citrus freshness into the drink. Stir again to ensure the zest is evenly distributed within the mixture.
To prepare the glasses, fill each with ice cubes until they are generously filled. Then, pour the elderflower citrus mixture over the ice, filling each glass about halfway.
Carefully top off each glass with sparkling water, adjusting the quantity to your liking for a fizzy touch. The addition of sparkling water will create a refreshing effervescence.
Using a long spoon, gently stir the contents of each glass to combine the flavors, taking care not to disturb the sparkling bubbles too much.
For the final touch, garnish each drink with a few fresh mint leaves. This not only enhances the drink's aroma but also adds a pop of vibrant green color.
Notes
For an elegant serving suggestion, use tall glasses and adorn each rim with a thin slice of fresh orange. Place a sprig of mint on top for a beautiful and inviting presentation.
