re: What to do with a dozen Carolina Reaper Pepper

I don't think you've got enough to bother dehydrating and crushing them. I'm not sure you'd even get a tablespoon of crushed flakes out of that. You could always mix that in with other crushed dried peppers, of course.

Mostly I'd just add them to different sauces. Or you could float one in some chili. One thing I'd definitely do is to deseed one, finely dice it, and add it to guacamole. I do that with habaneros all the time and it's great.
