Ingredients
  

  • 2 oz high-quality gin London Dry works exceptionally well
  • 1 oz fresh grapefruit juice preferably ruby red for color and sweetness
  • ½ oz simple syrup adjust to taste depending on grapefruit sweetness
  • ¼ oz fresh lime juice
  • 2-3 dashes of Angostura bitters optional but recommended
  • Ice cubes for shaking
  • Grapefruit twist or thin slice for garnish
  • Fresh rosemary sprig for garnish optional

Instructions
 

  • Prepare your glass by chilling a martini glass in the freezer for at least 5 minutes before mixing your cocktail. A properly chilled glass maintains the drink’s temperature longer.
  • Juice your citrus using a handheld juicer or reamer. Always use fresh grapefruit juice – the bottled stuff simply can’t compare in brightness and flavor.
  • Fill your cocktail shaker with ice cubes until it’s about two-thirds full. The ice quantity matters – too little won’t chill properly, too much will over-dilute.
  • Add all liquid ingredients to the shaker: gin, grapefruit juice, simple syrup, lime juice, and bitters if using. Make sure to measure precisely for balanced flavor.
  • Shake vigorously for 15-20 seconds until the outside of the shaker becomes frosty. This isn’t just for show – proper shaking achieves the right dilution and temperature.
  • Strain carefully into your chilled martini glass, using a fine mesh strainer if available to catch any small ice chips or pulp.
  • Garnish thoughtfully with a grapefruit twist or thin slice. For an aromatic touch, lightly pinch the rosemary sprig before placing it in the drink to release its essential oils.

Notes

  • For the most visually striking cocktail, use ruby red grapefruit, which produces a beautiful pink-hued drink.
  • The quality of gin dramatically impacts this cocktail. A gin with strong juniper and citrus notes (like Tanqueray or Hendrick’s) pairs perfectly with grapefruit.
  • This cocktail can be batched for parties – simply multiply ingredients and store in a sealed container in the refrigerator for up to 24 hours. Just shake with ice before serving.
  • For a lighter version, add a splash of soda water after straining into the glass.
  • Simple syrup can be made ahead by combining equal parts sugar and hot water, stirring until dissolved, and refrigerating.
