The spice and heat of peppers is measured in a Scoville Scale. According to the scale, the world's hotter pepper is currently the Carolina Reaper.
It was an American pharmacist Wilbur Scoville that first created the scale and it was therefore named after him.
Not sure if a certain chilli would be palatable for you, or if it could be hotter? You can check the scale and hopefully it will help… Good Luck!
But in the end it all comes down to how much heat can you take…. So how about it?
