I've been growing one type of chile pepper or another for over 20 years. I dry some, freeze others and turn more into salsas, sauces, and jelly.
The worst experience I ever had was when I put cherry peppers next to habaneros....the cherry peppers actually came out totally unedible. The cross pollination, totally accidental, was disastrous. We just went ahead and pulled up the entire row of cherry peppers.......
There was a BBQ place in Des Moines, IA (of all places) called Big Daddy's that specialized in Bahama "goat pepper" sauces. Big Daddy passed on a few years ago but the little restaurant still sells his stuff and its been picked up by the Hy Vee Grocery chain. Goat peppers and Habaneros look quite similar, like little Japanese lanterns. Its a good idea to handle them with a plastic grocery bag over your hand during the chopping routine and what ever you do, avoid getting the oil in your nose or eyes.
