Here’s what to do:
To infuse the vodka: combine half a bottle of vodka (375 ml) with 2-3 tea bags in a non-reactive container, giving it a shake periodically. Since the tannins in tea can quickly turn an infusion bitter, sample periodically. Tea infuses very quickly, so you may need only a couple of hours for a full infusion.
Combine all ingredients in a shaker filled ⅔ with ice. Shake well and strain into a chilled cocktail glass. Garnish with a dried orange slice floated on top. Enjoy!
