London: Vivek Singh, a London-based Indian chef, has created a dish that he says is the world's hottest curry. It is so hot it comes with a health warning.

Singh, who is the chef of The Cinnamon Club, has named his creation the Bollywood Burner - a lamb curry that was commissioned by Sir Richard Branson's Virgin Media to mark the launch of its new 'Bollywood On Demand' service.

Before ordering the curry diners are required to sign a disclaimer saying they are aware of the nature and risks involved with tasting the curry before eating it.

Inspired by Andhra cuisine, Singh uses the Naga pepper and its seeds, which, on the Scoville scale that measures the piquancy of peppers, has a figure of 855,000 - over 100 times hotter than the better-known jalapeno pepper.

"We found a list of the 10 hottest chillies and decided to try and use some of them. I think it will be the hottest curry in the world," said Singh.

But he said the Bollywood Burner may not regularly appear on the menu: "I would create it on demand for customers but will not include it all the time. I think it's just too extreme a dish."
