Question of the Day: Are banana peppers the same as pepperoncini?
Quick Answer: Though they both come from the Capsicum annuum family and are roughly the same size, banana peppers and pepperoncini differ in many ways. Banana peppers have smooth, waxy skins, and Pepperoncinis tend to be lumpy with valleys evident.
Pepperoncini and banana peppers also differ slightly in shape and taste. Banana peppers are more pointed with a sweet, mild flavor that has just a touch of tanginess. Pepperoncini tend to be more rounded on their ends, and though they are also sweet and mild, they have a slight, unmistakable bitterness.
