For one cocktail, you'll need:
- 2 oz vodka
- 1 oz fresh grapefruit juice
- 1/2 oz lime juice
- 1/2 oz simple syrup
- 3-4 sprigs fresh thyme
- 4-6 oz ginger beer
- Ice
- Grapefruit wedge and thyme sprig for garnish
Fresh juices are key for the best flavor. If grapefruits aren't in season, bottled juice can work in a pinch. The amount of simple syrup can be adjusted based on personal taste and the sweetness of your grapefruit.
