The Cobra's Fang strikes with tropical sweetness before the overproof rum's heat coils through, leaving a slow burn on the palate. Passionfruit and citrus provide bright, tangy relief, while falernum adds spiced depth and a whisper of absinthe lingers at the edges. The flamed cinnamon delivers a faint smokiness that threads through each sip, grounding the drink's otherwise sunny disposition with something darker and more complex.
