Jeff Blaine, 53, said he and restaurant owner Satish Sehgal, 62, are using the Naga jolokia, sometimes known as ghost chili, to create a sauce about 400 times spicier than store-bought Tabasco, the New York Daily News reported Monday.
Guinness World Records recognized Naga jolokia as the planet's spiciest chili in 2007.
"It's very, very hot," Blaine said. "How hot is hot? You can hallucinate from this chili."
He said the sauce will eventually be available for purchase.
"We want to call it 'Killer Sauce' but we're afraid -- if you're not used to this, it can be dangerous," Blaine said. "It'll be easy -- there's such a high demand for heat like this."
