Morrisons is launching an eight chilli rated curry – the Flaming Fiery Phaal – after listening to ‘curry regular’ customers who voiced complaints that the supermarket’s Volcanic Vindaloo was not hot enough.

The blistering phaal has been created by Morrisons’ chefs, who have scoured the country to find the hottest recipe possible. Their search led them to Birmingham’s Bangladeshi restaurants, the home of the phaal, which is often considered the fieriest and most challenging curry in the world.

A number of heat-hungry Morrisons customers sent reviews to Morrisons on the supermarket’s previous hottest curry – the Volcanic Vindaloo - deeming it ‘not hot enough’ and asking the supermarket to create ‘a much hotter version’.

Morrisons Barrow’s Flaming Fiery Phaal contains Scorpion Chillies which top the Scoville Heat Scale – which ranks how hot a chilli is – in addition to Naga and green chillies.

It boasts an eight chilli rating to make it the hottest supermarket curry ever.

Roger Taylor, at Morrisons Barrow, said: “We love to hear back from customers and were happy to take on the challenge. The difficulty when making a phaal is to make sure it’s got as much flavour as it has heat. But we think we’ve pulled it off!”

It will be available on shelf in Morrisons Barrow on The Strand for ‘Curry Week’, which began on Monday, and will cost £2.
