How hot is a Serrano Chile pepper?

Serrano peppers have a Scoville Heat Unit (SHU) rating of 8,000–23,000, which means they are considered medium-hot.

To give you an idea of how hot that is:

* Mild peppers: Bell peppers (0 SHU)

* Medium-hot peppers: Jalapeño peppers (2,500-8,000 SHU)

* Hot peppers: Habanero peppers (100,000-350,000 SHU)

* Very hot peppers: Ghost peppers (855,000-1,041,427 SHU)

So, Serrano peppers are definitely hotter than a jalapeño, but not as scorching as a habanero.
