Ghost Pepper (Bhut Jolokia)
The ghost pepper (aka the Bhut Jolokia) is one of the hottest peppers in the world, topping over 1 Million Scoville Heat Units.
It was awarded the distinction of the World's Hottest of All Spices by the Guinness World Records in 2006, topping the Red Savina Habanero, though was eventually toppled several times over. The current record holder for the hottest pepper in the world is the Carolina Reaper.
Ripe peppers measure 2.5 to 3.3 inches long and are usually red, though there are red, yellow, orange, white, purple or chocolate color varieties. They originate in Northern India and the peppers have been around for generations, though only cultivated in the western world since the turn of the century.
