What is Serrano Chili?
The serrano chili pepper is green when unripe and red when mature. Botanically speaking the serrano and all peppers are a fruit, but in the culinary world it is a vegetable. This hot pepper is about two inches long, thin and has a slightly tapered end. The thin, shiny skin protects the thin and firm flesh of the pepper. The inside is hollow and contains spicy hot seeds. The flesh is hotter than a jalapeño and on the heat scale it comes in at 10,000 - 23,000 heat units. The serrano is used to flavor dishes and is common in salsa.
