Serrano peppers are another variety of hot chili pepper and differ from other peppers in that they do not need to be steamed or peeled before use because of their thin walls. The Serrano pepper was first grown in the mountains of northern Puebla and Hidalgo in Mexico and is used for quick salads and salsas.
The name Serrano has the meaning ‘from the mountains’ in which it was first founded and grows best. The states of Veracruz, Sinaloa, Nayarit, and Tamaulipas are the biggest producers of Mexican Serrano chiles, growing about 180,000 tons of pods a year.
Serrano peppers are around 5 times spicier and hotter than jalapeno peppers at a fairly hot 10,000 – 20,000 scoville heat units on average. They come in red, brown, orange, and yellow depending on how long they are left on the stalk. Serrano’s grow to about 1 – 4 inches long and do not dry very well due to the fact Serrano’s are very meaty.
Serrano pepper plants grow to a height anywhere in between 24 – 36 inches tall and should be planted 18 – 24 inches in full sunlight. Water occasionally but do not over water and avoid peppers that are soft, bruised or have wrinkled skin or spots of mold.
