You DO realize of course that you are giving me LOTS of ideas for my Jalapeno Pepper Jelly (probably not until next year)? I might have to get some seeds & try a few of these ‘flavors’!!
I've been known to make pepper/onion relish but use bell peppers. Pretty sure it's a Ball Blue Book recipe for canning. Still have a couple of jars but the wife made the last batch and didn't simmer them long enough so the pepper chunks are still firm.
I'm growing Shisito peppers this year. Tried to start some bell peppers, Kalugarista peppers("jalapeno like heat") and those Pumpkin Spice Jalapenos but the seedlings did poorly. I just sowed two of each today for the heck of it and if the seedlings do better, I'll grow them in containers so I can control their climate by moving them if need be.
