Prepare Your Glass: Fill a cocktail glass with ice to chill while you prepare the drink.

Juice the Grapefruit: Squeeze fresh grapefruit juice until you have about 3 ounces. If you prefer a less bitter flavor, taste as you go.

Mix the Ingredients: In a cocktail shaker, combine the gin, fresh grapefruit juice, simple syrup, and lime juice.

Shake It Up: Add ice to the shaker, cover, and shake vigorously for about 15-20 seconds until well chilled.

Strain and Serve: Empty the ice from your chilled glass. Strain the mixture into the glass.

Garnish: Add a slice of grapefruit and a few fresh mint leaves for a pop of color and extra aroma.

Enjoy: Take a moment to appreciate the vibrant colors before taking your first sip.
