I have plenty of pepper leaves that's for sure. I wonder which species is best with Soy sauce and vinegar.

I think the reapers and ghost peppers are similar. I was not even sure they would be hot as this is the first year growing them. Damn impressed with the heat to the point of considering only adding one to my sauce so it is edible. Then I will give some ghosthabanero sauce to @parabyte and burn his ass off. ;)
