Juice the Orange: Start by juicing a fresh orange. You’ll want about 3-4 oz of fresh juice. If you have a juicer, great! If not, just squeeze it by hand. Fresh juice is key to giving this cocktail its signature brightness.
Add the Liquor: In a cocktail shaker, add the orange juice, triple sec, and vodka. If you don’t have a shaker, a mason jar with a lid works just as well.
Shake It Up: Add a handful of ice cubes to the shaker (or mason jar) and shake vigorously for about 10-15 seconds. You want it nice and cold.
Pour Over Ice: Fill a glass with ice cubes and strain the shaken mixture into the glass.
Top It Off: Add a splash of lemon-lime soda (or club soda if you prefer a less sweet cocktail) to give it a light, fizzy finish.
Garnish and Serve: Garnish with an orange slice for a little extra flair, and enjoy immediately!
