Dave's Hot Chicken in SoCal uses carolina reapers to spice their most spicy fried chicken. I really couldn't finish more than 1/3 of it. I've no idea how people eat this and remain unhurt.
dave's doesn't seem to do so any longer, but makes you sign a "waiver" for the hottest spice levels now even though they've toned it down quite a bit at this point. howlin' rays (which dave's copied) still uses carolina reapers and is no joke with it's howlin' spice level.
