The name of this cocktail came from the restaurant that it originated in – Post House restaurants, which were popular stops in Greyhound bus terminals.
What I love most about this recipe is it comes together with just 3 ingredients.
Combine the fresh grapefruit juice and vodka in a cocktail shaker. Add ice and shake until shaker is frosty.
strain the cocktail into a glass. I like to serve this drink over ice, but you.
Top your cocktail with sparkling water.
I like to garnish with fresh rosemary or thyme sprig and, of course, a grapefruit wedge.
