Wikipedia
The Bhut jolokia (, IPA: [ˈbʱʊt.zɔˌlɔkiˌja]), is also known as Ghost pepper, Ghost chili, U-morok, Red naga, Naga jolokia and Bih jolokia. It is closely related to the Naga morich of Bangladesh and is an interspecific hybrid chili pepper cultivated in the Indian states of Arunachal Pradesh, Assam, Nagaland and Manipur. It is a hybrid of Capsicum chinense and Capsicum frutescens.
In 2007, Guinness World Records certified that the Ghost pepper was the world's hottest chili pepper, 400 times hotter than Tabasco sauce. The Ghost chili is rated at more than 1 million Scoville heat units (SHUs). However, the Ghost chili was shortly superseded by the Infinity chili in 2011, followed by the Naga Viper, the Trinidad moruga scorpion in 2012, and the Carolina Reaper on August 7, 2013.
