What is a chili and why is it so special?
Belonging to the Capsicum genus , the chili pepper is a fruit whose main characteristic is the presence of capsaicin , the compound responsible for the spiciness that both fascinates and, at times, frightens. The chili pepper, also known as ajà or pimiento depending on the region, is distinguished not only by its heat but also by the wide variety of shapes, colors, and flavors it can have. It is an ancient ingredient, with more than 6.500 years of history, originally cultivated in the Americas and fundamental to the diet of pre-Hispanic cultures such as the Aztec.
After arriving in Europe with Christopher Columbus, chili peppers spread throughout the world, adapting to different cuisines and giving rise to countless varieties, each with its own distinct character. Not all chili peppers are hot : there are sweet, mild peppers with no trace of heat, and others so potent they can test even the bravest foodies.
Botanical classification of chili peppers
There are more than 250 varieties of chili peppers grouped into around 40 species, although only five are the most cultivated and well known:
- Capsicum annuum: Includes many of the most popular varieties worldwide, such as jalapeno, the cayenne or Bell pepper.
- Capsicum baccatum: It stands out for varieties such as Yellow pepper or mango chili, highly valued in South American cuisine.
- capsicum chinense: Here we find some of the hottest chilies on the planet, such as the habanero, Carolina reaper or Trinidad Moruga Scorpion.
- Capsicum frutescens: It includes chilies such as Tabasco, Naga jolokia or piri-piric, essential in the preparation of sauces and condiments.
- capsicum pubescens: Better known as hot pepper o crazy In South America, it is essential in Peruvian and Bolivian cuisine.
Chili peppers can vary considerably in appearance: immature ones are usually green or yellow , while as they mature they can turn red, purple, orange or even brown , depending on the variety.
The Scoville Scale: How is spiciness measured?
The famous spiciness level of chili peppers is determined by the Scoville scale , invented in 1912 by pharmacist Wilbur Scoville. This scale indicates the number of times a chili pepper extract needs to be diluted with sugar water for the heat to subside. Thus, a sweet pepper has 0 SHU (Scoville Heat Units), while varieties like the habanero or the Carolina Reaper can exceed one million units.
Capsaicin is especially concentrated in the seeds and inner veins of the fruit, so if you're looking for less spice, you can remove them before cooking or eating the chili.

Differences between fresh, dried, and smoked chilies
The same chili pepper can radically change in flavor, texture, and aroma depending on whether it's consumed fresh, dried, or smoked . For example, a fresh jalapeño is juicy and crisp, but when it transforms into a chipotle after the smoking process, it becomes dark, aromatic, with deep smoky notes, ideal for adding a special touch to meats and stews.
Many dried chiles, such as ancho, pasilla, or guajillo , are often rehydrated before being used in preparations like moles, adobos, or rich, complex sauces. Fresh chiles, on the other hand, are commonly used in simple sauces, salads, and dishes that require a direct burst of flavor.
How to choose the perfect chili for each dish
The key to unlocking the full potential of chili peppers lies in choosing the right variety for each recipe and desired result. Fresh chilies add a vibrant and refreshing touch , ideal for sauces, salads, ceviches, or as a filling. Dried chilies offer depth, sweetness, and complex smoky notes, essential in long-simmered stews, marinades , or moles. The level of spiciness is crucial: if you don't tolerate heat well, opt for mild varieties like bell peppers, piquillo peppers, or seedless jalapeños. For lovers of extreme heat, there are options that can elevate any dish to another level of intensity.
Nutritional benefits and interesting facts about chili
Aside from its flavor, chili peppers are an excellent source of vitamins A and C , carotenoids, fiber, and minerals. Capsaicin, in addition to causing the characteristic spiciness, has antioxidant and anti-inflammatory properties, and its potential effect on accelerating metabolism and reducing appetite is being studied.

Each variety contributes its unmistakable character: from the sweetness of the ancho chili, the freshness of the jalapeño, the smokiness of the chipotle, to the fiery heat of the habanero. Chili peppers are, ultimately, the spark and the soul of numerous dishes that form part of the identity of many countries.
