Every bar should have one or two drinks that walk away from their usual theme or clientele.  Burnt Bourbon is about as far from a tiki dink as you can get while still pleasing folks who truly enjoy good spirits.  An average bourbon and some smokey mezcal pair perfectly with pressed apple cider and cardamom.  Serve this to impress your relatives at Thanksgiving or any holiday.  Sip.  Savor.  Enjoy.
