There's a pepper forum here on Garden Web too, you might ask there.
I just use my favorite dill pickle recipe. Adjust your spices to your taste. You can increase the vinegar ration (up to 100%), but don't decrease.

See the Husband need dill pickle help thread.

Yeah, just substitute your 5 lbs of sweet bananas in that recipe.

I would taste the brine, though, before discarding the sugar. That's fairly vinegar heavy and you might need the sugar to cut the sharpness just a hair.

I don't know what the directions say. But if you'll be pickling them whole, be sure and put a slit in each pod so the brine can reach the inside.

Hey Gardenlad, it says, "Small peppers may be left whole with two small slits in each pepper. Core and cut large peppers into strips."

Am I right that the larger the pepper, the greater the percentage of seeds and core, so it's not just a matter of whether the peppers will fit into the jars?

I KNOW this may be just unbearable to all of you experts, but, here goes:

Not including stems, the longest are 6 inches; the smallest about 4.5 inches. Would any of those be considered "small?"

Since this is to be a nap time endeavor and time will be short, can I just cut them in half lengthwise and remove the seeds, etc.

Also, I don't see any real info on how tightly to pack them in the jars. Is it pretty much like for pickles, or not as tight?
