When to Pick Serrano Peppers: The Red Hot Chile Peppers

In the Americas, when we talk about peppers, we usually associate it with Mexico. From this country south of the border, you can find peppers of assorted varieties. No matter what variety, they can really excite the taste buds. Some are sweet, some hot and some really, really hot. Perhaps the most popular of these is the jalapeno pepper. It is widely used in salsas, enchiladas, tacos, burritos and in everything Mexican.

Closely related to the jalapeno is the Serrano pepper. It looks exactly like the jalapeno but is smaller, about 1-4 inches in length and half an inch wide. Some kinds can grow even bigger.

These peppers are usually green but may also be brown, red, yellow or orange. Because the Serrano is a meaty pepper, it is not an ideal choice for drying. It is best used fresh. One important property of this small pepper is that they can pack a kick and are a lot hotter than the jalapeno.

Like the jalapeno, the Serrano appears in many Mexican dishes. These include salsas, garnishes, relishes, and more. Their flavors become more intense when roasted. Jalapenos may bite but Serrano peppers will kick. This small pepper is always a welcome addition to many meals either solo or in dishes.

The History Of Serrano Peppers

Because of its intensely hot property, Mexicans use the Serrano to flavor many dishes. This pepper has appeared in Mexican dishes for centuries.

It has rooted itself in almost all its cuisine. They originated from the mountainous Mexican states of Puebla and Hidalgo. "Sierra" is the Spanish term for mountain. And the term Serrano is just a derivative of the word.

The walls of the Serrano peppers are relatively thin. These will change color to either red, orange, brown or yellow when they ripen. Here are some signs to look for to indicate that the pepper is ripe:


The different colors of the pepper will also indicate its degree of heat. The peppers start green and change color as they ripen. From green, they become yellow, orange, brown or red. You can therefore do your picking whenever the color you want appears.

Two to three inches is the average length of the Serrano pepper. They are however harvested when they are 3-5 inches in length and half an inch wide.

Among gardeners and users, this is the usual size. But bear in mind that the size will also determine the pepper's flavor and heat level. The smaller the pepper, the more heat it will pack.


The best season to plant the Serrano peppers is during warm conditions. The reason for this is that these peppers have a propensity for warm weather. You need to make a plan when growing Serrano peppers. Time it by picking the right months when the hottest temperatures occur.


There isn't much difference if the pepper's skin is thin or thick. They would still release the same heat and flavor, regardless of the skin's thickness. It is not even a factor in ripeness. But it is significant when preparing it for cooking.

Thin-skinned varieties of these peppers are easier to peel. This means that they are also much easier to prepare. In fact, some do not peel them anymore. Thick-skinned peppers are harder to prepare. However, many people still prefer the peppers with thick skins. Thick ones add some crunch in dishes like Pico de Gallo and salsas.
