The Serrano chili pepper is a distinctive chili pepper well-known for its small, torpedo-like shape. They're most popularly used in Mexican dishes and commonly eaten raw, roasted and pickled.
Serrano peppers are usually between one and four inches long and half an inch wide, making it a bit smaller than a jalapeño. Serranos can be found in a variety of colors, including green, red, yellow, orange, and brown. The different colors don't indicate different types of peppers, but rather the stage at which they were picked. For instance, green Serrano peppers will have a milder flavor, while orange and red peppers will have a more developed, spicier flavor.
A serrano chili pepper has an average rating of 20,000 Scoville Heat Units which is hotter than our jalapeño on the Scoville Scale.
