There are a few chili peppers as aptly named as the fatalii pepper. Obviously, its not fatal to eat a fatalii, but its definitely one of the hottest peppers in the world. But what makes this chili extra special is whats behind the quick sting. Theres a unique citrusy flavor thats simply tasty. Its the perfect hot pepper for citrus hot sauces and salsas, as well as dishes where lemon or lime is a critical component.
