I kinda get where your coming from on the Sriracha but I use it once in a while. Its actually pretty good on a ham sandwich! To me it is just a very sweet, garlic-ee, Fresno pepper hot sauce, but I want to try a Ghost Pepper version for the heck of it.
Otherwise, been reading about fermenting hot peppers and for some reason I thought that fermenting resulted in hot sauce that kept far longer than the stove top version I usually make (which I have always enjoyed), so the fermented hot sauce might not do much for me - we'll see.
Nevertheless, I am down for some home made pickles and sauerkraut and maybe some kimchi - maybe...
