In 2013, the Guinness Book of World Records designated the Carolina Reaper as the hottest pepper in the world. “By comparison, a jalapeño is probably 10,000 to 15,000 Scoville units,” Calloway says.
They used gas chromatography to separate the capsaicinoids, and a set of pungency values that related capsaicinoid concentration to Scoville’s original dilution factor.Īfter years of testing, through various seasons and analyses of different plots and varieties, Calloway and his team concluded that the Carolina Reaper averaged a Scoville value of 1.569 million, though it could go as high as 2.2 million. So for example, a solution diluted by 1,000 times meant the pepper’s Scoville number was 1,000.īy the 1970s, analytical chemists modified the technique to make it less subjective and more standardized. The factor required to dilute the solution to the point where he sensed no heat was that pepper’s Scoville number. “He came up with this idea to take a pepper extract and dilute it, and dilute it again and taste it, dilute it again and taste it,” over and over again, Calloway says. The Scoville scale was developed by pharmacist Wilbur Scoville more than 100 years ago as a quantitative measurement for how hot chili peppers were. The more of a capsaicinoid there is, the more light that gets absorbed, and the greater the signal from the detector.īased on the strength of those signals, chemists can determine the concentration of each capsaicinoid, and from there, calculate the pepper’s Scoville value - that is, its heat level. The system is also equipped with a detector that measures the amount of UV light absorbed by each capsaicinoid. They used a high-performance liquid chromatography system, a chemical process that can separate the capsaicinoid compounds from other substances in the pepper. Then he worked with Calloway and his students at Winthrop to test and analyze the pepper’s heat value. (Currie, by the way, recommends citric acid - like lemon juice - to help ice the fire.)Ĭurrie first cultivated the Carolina Reaper in 2004, crossing a Naga pepper from Pakistan with an habanero pepper from the island of St. And the cooldown can take a little while - expect about half an hour before the heat sensation dissipates. The heat is so bad, it feels good - Currie says Reaper consumers sometimes experience something like a runner’s high. That’s the best way to put it,” Currie says. And then immediately, that vast amount of capsaicin takes over, and it’s kind of like eating molten lava. “When you bite into it, the initial taste is sweet. “So even though it’s not really a chemical burn, like getting burned by a match or a flame or anything like that, your nerve cells get the signal from the capsaicin ‘key’ to make them think that they’re getting burned,” says Calloway.īy packing his Carolina Reaper with capsaicinoids, Currie inadvertently concocted a very, very hot pepper. “It kind of fits into these little nerve cells in your tongue,” he explains, and when that happens, you perceive the sensation of heat. Of those compounds, capsaicin is the most common.Ĭliff Calloway, a chemistry professor at Winthrop University in South Carolina, says the capsaicin molecule looks like a key, with a round end and a tail coming out of it, and acts like one, too. Currie had heard they might be useful in treating cancer or heart disease (any solid proof of this remains elusive, though Currie is optimistic).īut capsaicinoids are also what make chili peppers hot. His initial aim was to produce a pepper packed with capsaicinoids, a family of compounds that has been used in pharmaceuticals such as arthritis creams. “I was very surprised.”Ĭurrie, who’s the founder of the PuckerButt Pepper Company and cultivator of the Carolina Reaper, says he wasn’t trying to create the hottest pepper in the world.
Add your spices and lime juice at this time.The first time Ed Currie tasted the Carolina Reaper, a fire-engine red chili pepper the size of a golf ball, “it knocked me to my knees,” he says.
In a mixing bowl or blender, blend or whisk all ingredients together until honey has dissolved.Push puree through a wire mesh sieve to remove any large bits of pepper.
Puree to a fine paste, adding vinegar liquid as needed. Add garlic, chiles, and salt to a food processor or blender. Cover and simmer on low heat for approximately 1 hour or until Guajillos are rehydrated and tender.
