The Serrano pepper (Capsicum annuum) is a type of chili pepper native to the mountainous regions of the Mexican states of Puebla and Hidalgo. The name serrano is taken from the Spanish word for mountain, sierra. The plants vary in length from about half a meter to one and a half meters. One plant can yield a harvest of fifty peppers. Ripe serrano peppers can come in a variety of colors: green, red, brown, orange, or yellow (this variety is green). They are crispy and pungent in taste, significantly hotter than the comparable Jalapeño.
