Bhut Jolokia ( Ghost chilli) is native to the NE states of India such as Nagaland, Manipur, Mizoram, Assam and Sikkim. The chilli is small in size but packs a punch of heat at 350000 to 400000 Scoville heat units. Some variants can go as high as 800000 Scoville heat units.
Use on dishes by sprinkling a little or temper them in a little oil and use the oil for the spicy flavour.
Caution: Use gloves while handling and keep them out of reach of children.
