What is "banana pepper"

n. A kind of yellow chili pepper, ''Capsicum annuum''.

The banana pepper (also known as the yellow wax pepper or banana chili) is a medium-sized member of the chili pepper family that has a mild, tangy taste. While typically bright yellow, it is possible for them to change to green, red, or orange as they ripen. It is often pickled, stuffed or used as a raw ingredient in foods. It is a cultivar of the species Capsicum annuum. Its flavor is not very hot (0–500 Scoville units), and as is the case with most peppers, its heat depends on the maturity of the pepper, with the ripest being sweeter than younger ones.
