If you can get your hands on some ruby red grapefruits and fresh thyme then this cocktail will be worth the effort. The only real effort is infusing the simple syrup with fresh thyme and even that isn’t that big of a deal. The thyme adds a subtle woody taste to the margarita which I really liked.
In a saucepan over medium heat combine water and sugar. Allow the sugar to melt, for making a simple syrup. Add 2 sprigs of thyme. Remove from heat and let cool. Leave the sprigs inside the syrup. Reserve.
Juice the grapefruits and strain to remove the pulp.
In a cocktail shaker add ruby red grapefruit juice, tequila reposado, 3 ounces of thyme-infused simple syrup, lime juice, and ice. Shake and pour into a sugar-rimmed cocktail glass. Garnish with a slice of lime and a sprig of fresh thyme.
Notes
For this recipe, I recommend Reposado! The smokiness of the Reposado has a nice finish when combined with the sweet and tangy grapefruit and the thyme infused syrup.
