In the middle of our lab, a cauldron boiling. Amber leaves of rooibos flicker, then flakes of pumpkin make the gruel thicker. A fuming broth of caramel sizzles, while a sliver of blackberry shoot fizzles. Three stinging droplets of vanilla smolder. Featuring August Uncommon Tea, this intoxicating, buttery concoction will satiate your deepest, darkest PSL desires.
