The Hellfire Burger from Xtreme Smokehouse isn’t exactly comfort food. There may be a good two or three seconds of warm and fuzzy when you first bite into it. That’s when the honeymoon ends and unadulterated mouth-terror kicks in. At a claimed 1 million SHU, the Hellfire may be the hottest hunk of ground beef ever tucked between two buns. Outside of the porn industry, that is. For point of reference, Ed Currie’s Carolina Reaper, the hottest pepper on Earth, clocks in at 1.5 million SHU. American pepper spray weighs in at 2 million SHU. Conquering a Hellfire Burger is asking a lot of digestive system. In fact, you should probably buy it flowers and wine before you even ask it to process the thing.
