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.                                                      –WO
