Latin American cuisine uses hundreds of varieties of peppers to create beloved smoky and spicy dishes that transcend borders -- from poblanos to jalapenos to pasillas. Why, you ask? Well, not only do they add flavor, but peppers are actually good for you! The vitamins and minerals they contain can potentially serve anti-bacterial and anti-carcinogenic purposes. But watch out for the peppers on this list, as their high rankings on the Scoville scale (used to measure that familiar spicy heat) mean they are no joke. Consider yourself warned; a bite of any one of these rare little guys will get you a one-way ticket to the emergency room, so proceed with caution.
