Creating the Rosemary-Grapefruit Paloma Mocktail can be both fun and easy if you follow these straightforward steps:

1. Prepare Grapefruit Juice: Squeeze the grapefruit to yield about one cup of fresh juice. Strain if desired to remove pulp.
2. Infuse Rosemary: In a small saucepan, heat a cup of water and add a sprig of fresh rosemary. Allow it to simmer gently for 5 minutes to create a rosemary infusion.
3. Mix Ingredients: In a large glass or pitcher, combine the freshly squeezed grapefruit juice, agave syrup (or honey), and the rosemary infusion (removing the rosemary sprig from the water).
4. Add Sparkling Water: Gently stir in the sparkling water to maintain its fizziness and lightness.
5. Serve Over Ice: Fill glasses with ice cubes and pour the mocktail mixture over the ice, filling each glass.
6. Garnish: Garnish each drink with a slice of grapefruit and a sprig of fresh rosemary for added aesthetics and flavor.
7. Enjoy Immediately: Serve the Rosemary-Grapefruit Paloma Mocktail immediately for the best experience.

Following these easy instructions will guarantee that you enjoy a refreshing and delicious mocktail that stands out at any gathering!
