This recipe looks amazing! I’ll have to give it a try. 
Once upon a time, my DH decided to make his own chili powder with ghost peppers. (There’s a story about his boss claiming to have an iron clad stomach and no chili was ever hot enough for him, which my DH, the Texan, took as a personal challenge.) So my DH dried his collection of peppers on the grill and brought them inside to crush into powder in the blender. Long story short, he ended up macing himself with the fumes from the still hot peppers.
Yeah…he hasn’t attempted that again.
