Sport peppers

Sport peppers are mild chili peppers that are especially popular in the Southern United States and Chicago. They're a key element of the popular Chicago-style hot dog. The peppers have a Scoville Heat Unit ranging from 10,000 to 23,000 and they're typically pickled in vinegar.

After they've been pickled, these green peppers turn pale green. The flavor is slightly spicy, tangy, and vinegary. Although they are believed to originate in Mexico, the name sport can refer to a variety of pickled peppers from the same family, but their most known usage is in Chicago and the American South.
