For the Simple Syrup:

1. In a small saucepan, combine the thyme sprigs, sugar, and water. Bring to a boil over medium heat. Reduce the heat and simmer, stirring occasionally, until the sugar has dissolved, about 5 minutes. Remove the pan from the heat and allow the syrup to cool completely. Can be made ahead and stored in an airtight container in the fridge.

For the Cocktails:

1. Squeeze the juice of the grapefruit into a shaker filled with ice.
2. Add the vodka, gin, and 1-2 tablespoons of the simple syrup (to taste – shake, taste, and add more if not sweet enough).
3. Shake well and pour into two chilled glasses.
4. Top each off with a little club soda and garnish with fresh thyme sprigs, grapefruit slices, and pomegranate arils (all optional but super festive!).
