Know your Serrano Pepper

  • The serrano pepper (Capsicum annuum) is a type of chili pepper that originated in the mountainous regions of the Mexican states of Puebla and Hidalgo. 

  • Unripe serranos are green, but the colour at maturity varies. 

  • Common colours are green, red, brown, orange, or yellow. 

  • Choose chiles with deep colours, avoiding those that look wrinkled or soft.

  • When pickled they are known as a sport pepper. 

  • Their flavour is crisp, bright, and biting, notably hotter than the Jalapeño pepper they resemble, and they are typically eaten raw. 

  • Though not as hot as the infamous habañeros, serrano peppers deliver plenty of heat and are the easiest hot chiles to obtain. 

  • These dark green or red peppers are between 1 and 2 inches (2.5–5 cm) in length and about 1/2 inch (1.3cm) in diameter, with a slight taper and a rounded end. 

  • The larger variety, termed the Largo, can be twice this size.

  • As a general rule of thumb, the smaller the Serrano pepper, the hotter it will taste.

  • Serrano chiles are extremely hot peppers that range in heat between 5,000 and 20,000 Scoville heat units.
