At SXSW, I had the extreme pleasure of eating Nuclear Tacos. I don't use the word "pleasure" lightly -- these tacos are made with Red Savina Habanero chiles. They're genetically engineered for extreme heat -- over 570K Scoville units (65 times hotter than jalepeno) -- which causes a "runner's high" during consumption.
I'm constantly forgetting the name of these peppers, so I'm stashing this post here as a reminder to myself, and perhaps to turn on other chile lovers. Try 'em, you won't regret it.
