Finger shaped, easy to dry, pick green or red. The serrano chili pepper is a smaller version of the jalapeño pepper, similar in color, but smaller, about 1 to 4 inches long on average and 1/2 inch wide. They generally grow between 1 – 4 inches long and about 1/2 inch wide though they have been known to grow longer.
They are meaty peppers and are not the best choice for drying. The serrano pepper originated in the Mexican states of Puebla and Hidalgo. They are commonly red, brown, orange, or yellow, though you are likely to find them in their more common green color, much like a jalapeno pepper.
Serrano peppers are perfect for salsas, sauces, relishes, garnishes, and more. They are usually best when roasted. I personally love serrano peppers for their delicious spicy kick. Where a jalapeno has a nice bite to it, the serrano steps it up a nice level, and has a fresh flavor similar to the jalapeno. Roasted serrano peppers are delicious and make a welcomed addition to many a meal.
