Prep: 1. Make simple syrup by combining sugar, water, and 4 sprigs of lemon thyme in a saucepan. Bring to a boil for 1 minute, strain and let cool. 2. Cut lemon into wedges. Make: 1. For each drink, muddle 2 lemon wedges in a shaker or mason jar, use a wooden spoon if you don't have a muddler (make sure the lemon skins start to break up). 2. Add 2 ounces of cooled simple syrup, 2 ounces vodka, and a few ice cubes. Place lid on shaker or jar and shake well. 3. Fill a glass 2/3 with ice and pour shaken drink into glass (no need to strain). 4. Top with 2 ounces of club soda (or more to taste).
