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 However, the ghost chili was shortly superseded by the Infinity chili in 2011, followed by the Naga Viper, the Trinidad moruga scorpion in 2012, and the Carolina Reaper on August 7, 2013.
Please note - without wishing to sound like some sort of marketing ploy, we cannot stress enough how potent this stuff is. So please when handling take extra care with it. We strongly advise the wearing of gloves, and a respirator or mask to avoid inhaling particles or fumes when cooking. The smallest amount of this powder on the skin, or worse still in the eyes or inhaled, can cause serious irritation. In food though, it's exceptional!
