I cooked half of one in a mixed vegetable dish and it added serious heat.
I use habaneros in chili, in hot Mexican cheese dip (which is a big holiday pot luck winner, half the folks at most parties love it the other half won't taste it) and in omelets. I will use the Bhut peppers in those . I got a few from a friend who grew them I am going to dry them out and try to plant the seeds next spring to grow my own.
Hot pepper does stimulate stomach acid so if you have an ulcer it can make it worse but it doesn't actually burn the skin, just stimulates the pain and heat receptors in the nerves to fool the body into thinking it is being burnt. The heat and pain receptors use the same nerve fibers so both are stimulated at the same time. Blistering from hot peppers is a result of the body being fooled so it is not really common. No flesh is actually being harmed by the hot pepper you just think it is. It is very true (from bitter experience) that the peppers do pass through into the stool and eliminating them can be VERY painful.
