How to Make It
Spread the sugar in a shallow dish. Moisten the rim of a highball glass with water and dip the rim in the sugar to coat. Fill the glass with ice.
In a cocktail shaker, muddle the lemon wedges with the Lemon-Thyme Syrup. Add 1 cup of ice and the vodka and shake well. Strain the vodka mixture into the highball glass and top with club soda. Garnish with the thyme sprig and serve.
