Everything mentioned in this thread is just rank and file compared to the original, one-and-only, Dave's Insanity Sauce.
Back in the 90s this was the only commercial brand hot sauce actually banned from sanctioned hot sauce competitions. The product is still in the market, and has expanded to additional flavors. I've seen one drop off this stuff make a 5 gal pot of chili plenty hot. A 2nd drop ruined it, so hot nobody could get through a spoon.
Maybe they've dumbed it down since those days. I hope so. Otherwise, do not eff with this product. Litterally, it used to be so dangerous, the sauce bottle came with an actual DOT hazmat label to warn the buyer of measured reactivity.
