The Fatalii is a cultivar of the chilli pepper Capsicum chinense developed in southern or central Africa from chilies introduced from the Americas. It is described as having a fruity, citrus flavor with a searing heat (rated by the Scoville Food Institute as the sixth hottest) comparable to the habanero, to which it is related and from which it was probably derived.
When eating a whole white chili and chewing for at least 10 seconds before swallowing (not recommended for untrained tasters) the heat may be first felt aggressively in the back of the throat, up the nose, then eventually moves to the roof of the mouth and finally the tongue where the pain is intense, at which point there can be gustatory sweating and tears from the eyes. Some tasters note the strong, fruity Fatalii flavour, which is quite distinct, as being almost identical to the yellow version. Others find it milder.
