Serrano

The chile that's smaller and hotter than a Jalapeno. The Serrano's life
cycle resembles a leaf's: It starts out as a bright, light to dark green
chile, and turns red, brown, orange, or yellow as it ripens. Since it's
the hottest chile readily available in the United States, your local
grocery store should stock the Serrano. Buy them either fresh or
pickled. Use fresh ones to make salsa Verde and Pico de Gallo,
and try pickled ones for a zesty condiment.
