I don’t do extract sauces as a general rule (don’t have any actual good flavor just heat) and a lot of those 5 flame ones are extract sauces.
I do have the Garlic Reaper and Reaper Evil off that list which are non-extract sauces and are very tasty. I also have Reaper Squeezins which is just 92% Carolina Reaper mash and 8% distilled vinegar. (It’s actually hotter than Reaper Evil and Garlic Reaper and the other Puckerbutt sauces that make the 5 flame list, but isn’t actually on the list itself.) Edit: appears they don’t even carry Reaper Squeezins for some reason. If they did it would def be in that group. I have several Scorpion sauces and a 7 Pot Primo sauce that are right up there with those for heat level.
Over the years I have naturally built up some tolerance to the “super hots” but I usually use them to add depth and complexity to dips, soups, sauces and marinades rather than using them directly on food. When I get new ones I usually like to try them on cheese and crackers or summer sausage to get a feel for how to use them though. Most of this new batch I just got is on the lower end of the heat spectrum and focused more on balance and flavor for every day use.
Carolina Reapers are surprisingly sweet and fruity at first taste and can kind of lull a person into a false sense of security. I’ve found myself having second, third, fourth helpings thinking everything was fine and then all of sudden the wall of heat and associated endorphin rush hits. 🤯
I recently have made similar sized orders from Heatonist, Puckerbutt Pepper Co and Heat Hot Sauce Shop and all have have been great except one sauce that I hated the taste so much I actually dumped it out so I could reuse the bottle for a homemade sauce I had in a Pyrex dish. I think I’m probably good for a while now.
