Chilli peppers are surely one the world’s great mysteries. On paper, objectively, they are horrible. They burn the tongue, set the face on fire and bring to tears to the eyes. Yet, when experienced, they surely count among life’s truest pleasures. From hot wings to hot and sour soup, from pizzas and nachos to the very best curries, there is little, it seems, that cannot be made better by adding some variety of chilli pepper, the hotter the better.
