New peanut butter not for the faint-hearted

A new spicy variety of peanut butter - six times hotter than the world's hottest chilli - is to be sold in Britain.

The aptly named Instant Regret peanut butter is packed with capsaicin - the component that provides the heat within a chilli.

On the Scoville scale, which measures the heat of chilli peppers, the peanut butter boasts a whopping rating of 12,000,000.

To put this in perspective, the world's hottest chilli - the Moruga Scorpion - rates at 2,000,000, as does the most legal variant of pepper spray.

The spread is not for the faint-hearted and even comes with a warning to users. It is not suitable for the elderly nor children.

So fiercely hot is the butter that the retailers, Firebox, had to persuade the factory to produce it.

Instant Regret creator Ben Redhead said: "During the tasting process we first laughed, but then we cried.

"Measuring a mental 12 million SHU on the Scoville Scale, it's probably not your everyday breakfast spread."

For anyone brave enough to give it a try, the peanut butter is for sale online at £7 a jar.
