I've got something called "Insanity Sauce" don't think it's "Daves" though. When i go to the indian etc i ask for it to be as hot as they can make it and its never hot enough. When my partner bought some "hot sauce" from the supermarket i put a quarter of a bottle on my dinner as normal, then realised its the hottest thing i'd tasted. Love it though, although more than say a tea spoon on a meal and you can feel it burning your stomach so you have to go steady, surely theres no hotter than that?

Edit, just looked at the pic on the net and it is "Daves" what we've got.
