Mexican cuisine is renowned worldwide for its bold, intense flavors. A key ingredient that provides that signature heat and depth of flavor is chili peppers. Chile peppers are a diverse group of spicy varieties that belong to the plant genus Capsicum and can range from mild to blisteringly hot on the Scoville scale. While there are many types of chiles used in authentic Mexican cooking, four, in particular, stand out as being the most popular and influential. These four famous chiles used in Mexican cuisine are ancho, jalapeño, habanero, and chipotle.
What is the Ancho Chile?
The ancho chile is a mild to medium hot chili that measures 3 to 5 inches long. It is a dried form of the fresh poblano chili. Ancho chiles are deep reddish brown in color and have a wrinkled appearance from the drying process. They have a rich, earthy flavor with notes of dried fruit and subtle hints of smoke and spice.
Some key facts about the ancho chile:
- Scoville rating: 1,000 to 1,500 SHU
- Other names: Chilaca, chile negro
- Common uses in Mexican cuisine: Mole sauces, chili con carne, tamales
The ancho chili is one of the most widely used dried chiles in Mexican cooking. Its mild heat works well in complex moles, stews, and sauces, adding a backbone of smoky chili flavor without overwhelming spice. The versatility of the ancho chile makes it an essential ingredient in classics like mole poblano and carne adovada.
What is the Jalapeño Chile?
The jalapeño is probably the most popular and recognizable chili pepper in Mexican cuisine. Named after the town of Jalapa in the state of Veracruz, these small tapered green chilies pack quite a punch.
- Scoville rating: 2,500 to 10,000 SHU
- Other names: Cuaresmeño
- Common uses in Mexican cuisine: Salsas, guacamole, chiles rellenos, elotes
Bright, grassy and vegetal when fresh, jalapeños take on notes of red chili flavor when matured to a deep red color. They have a biting heat that hits the palate instantly. Both fresh and pickled jalapeños are integral ingredients in salsas, guacamoles, and grilled street foods like elotes (Mexican street corn).
What is the Habanero Chile?
The habanero chili is an extremely hot variety smoldering at 100,000 to 350,000 Scoville heat units when fully mature. These chiles are identified by their distinctive lantern shape and vibrant colors ranging from green to orange and red.
- Scoville rating: 100,000 to 350,000 SHU
- Other names: Chiltepin, Scotch bonnet
- Common uses in Mexican cuisine: Hot sauces, salsas, soups, stews
While incendiary in their raw form, when used sparingly in cooking habaneros take on a complex fruity flavor. The habanero packs a mean punch of heat that turbocharges salsas, hot sauces, andregional specialties like cochinita pibil from the Yucatán Peninsula.
What is the Chipotle Chile?
The chipotle chili is a smoked and dried version of the jalapeño pepper. Chipotles are made by allowing jalapeños to ripen to a deep red on the vine before being harvested and dried over a smoldering fire.
- Scoville rating: 10,000 SHU
- Other names: Chile ahumado, chile meco
- Common uses in Mexican cuisine: Adobos, salsas, soups, stews, meats
The smoking process imbues the chiles with a deep, earthy raisin-like flavor. While hot, chipotles have a slower building heat compared to fresh chiles. Their complex smokiness enhances slow-cooked dishes like chili con carne. Chipotles are most often used in adobo sauce, where they are stewed in a vinegar and tomato sauce.
