Ingredients:
- Grapefruit juice
- Mint leaves
- Simple syrup

Instructions:
Step 1: Cut the grapefruit in half and squeeze the juice into a bowl. Step 2: Place the mint leaves in a glass and muddle them gently with a muddler or the back of a spoon to release their oils. Step 3: Add the simple syrup to the bowl with the grapefruit juice and stir until well combined. Step 4: Pour the mixture into a cocktail shaker filled with ice. Step 5: Top the shaker off with club soda and shake vigorously for about 10-15 seconds to combine and chill the ingredients. Step 6: Strain the mixture into a chilled glass and garnish with additional mint leaves or a sprig, if desired.
