Bhut Jolokia peppers
Nicknamed the ?ghost pepper? for its reputation to cause people to ?give up the ghost,? this wrinkly, red, supernaturally hot hybrid was once considered the hottest in the world, with 855,000?1,000,000 Scoville heat units (a title now held by the Trinidad Moruga Scorpion, with 2,000,000 SHU). So, how hot is it? With roughly 400 times as much capsaicin as a jalapeño, it is used as elephant repellant in India. In short, proceed with extreme caution!
