When drying habanero peppers in a food dehydrator, be sure to place the food dehydrator OUTSIDE (or be prepared for the wrath of your family.)
If you accidently pass your hand over the food dehydrator exhaust while drying habanero peppers, WASH YOUR HANDS IMMEDIATELY. There is enough pepper oil in the exhaust to burn the tar out of your eyes and face.
After you dry habanero peppers in your food dehydrator, make sure to wipe down all surfaces with alcohol. There is enough residual oil on surfaces of the unit to HURT YOU.
If you grind habanero peppers in a mill, be prepared for pain. Do it outside and stand upwind from the mill. Wear chemical proof rubber gloves and a mask. Eye protection is recommended.
Freshly dehydrated habanero peppers have a lot more oil in them than the stuff you buy in stores. Be careful.
