Fill a tall glass with ice. Add tea, orange juice, and fireball whisky. Stir to combine. Optionally, shake in a cocktail shaker and pour over ice.
Optionally, garnish with an orange slice. Serve immediately.
Sweet or unsweet tea can be used in this recipe, based on your personal preferences. Using unsweet tea will lower the calories and sugar. If using fresh oranges, one orange contains about 2 ounces of juice. Plan to use one orange for every drink made, plus extra for garnish.
