I did a Hab Sauce last year that was awesome.
I pureed a lot of peppers, a carrot and an onion in my food processor then steeped it in vinegar for a bit. Put it back in the food processor, strained the seeds out and canned it.
I had to open up every window and door in the house and had fans going... We couldn't breath otherwise... If I do it again, I'm getting a respirator and goggles. Also, wear gloves!!! PPE is important and oils will make you uncomfortable or even burn you.
