Chili peppers are fundamental flavour-building ingredients in Mexican cuisine, and learning how to use them well can help you achieve spectacular results in the kitchen.
Ancho chilies, are dried, ripe poblano peppers. Ancho chilies, like fresh poblanos, are generally low in heat, with a distinctively sweet and raisin-like fruity flavour.
Ancho chilies are extremely popular, and are often given a starring role in dishes. Like all of the Holy Trinity peppers, they feature in many moles and sauces, but they are also very popular across a broad range of Mexican, Tex-Mex, and fusion dishes. They also tend to be a little easier to find that some of the peppers on this list.
SHU: 1,000-2,000 (fairly mild)
Mulato chilies, are dried variety of poblano pepper, picked when very ripe. Mulato chilies are moderately hot, with a sweet, fruity, slightly smoky flavour. They’re highly appreciated for the distinctive chocolate/cherry/licorice notes that they impart to a dish.
Mulato chilies are generally the hottest member of the Holy Trinity, though pasillas can sometimes approach the same level of spice. Mulato chilies are extremely popular in Mexico, but are not as well known outside of the country.
SHU: 2,500-3,000 (moderate)
Pasilla chilies, are dried, ripe, chilaca peppers. Pasillas are elongate, thin, and tapering, with wrinkled, nearly black skin. Their flavour is fairly similar to that of an ancho chili, with raisin and coffee notes. They also tend to be a little hotter than ancho chilies.
Pasilla chilies are the victims of frequent mis-labeling, and are often confused with anchos and (oddly) fresh poblanos. True pasilla peppers can be a little harder to find than some of the other peppers on this list.
SHU: 1,000-4,000 (mild-to-moderate)
Cascabel chilies are dried bola (round) mirasol chili peppers. Cascabel means rattle in Spanish, a reference to the shape and the way the seeds rattle inside of the hollow pepper. Cascabels contribute a very fruity, slightly smoky flavour to dishes without contributing a great deal of heat. Their distinctive, likable, and easy-to-spot appearance makes them a popular and relatively easy to find pepper
Cascabels are mild-to-moderate in terms of spice, and can often be used by spice-averse cooks in place of hotter peppers.
SHU: 1,500-2,500 (mild/moderate)
Guajillo chilies are relatively large, long, and flat dried mirasol chili peppers. Guajillos contribute a sharp, fruity, somewhat tangy flavour to dishes without contributing a great deal of heat. They’re a fairly common and popular pepper in Mexican cooking, though they tend not to be as quite well-known/used outside of Mexico.
Guajillos are moderately spicy, and fairly comparable to a cascabel or chipotle pepper of the same size. They’re my personal favourite chili in this category.
SHU: 2,500-5,000 (moderate)
Puya chilies are relatively long, thin, dried mirasol chili peppers. Puyas are similar to guajillos in terms of flavour, but hotter. Puyas have a wonderful flavour, and are perhaps the best all-purpose red chili to use if you’re a fan of hotter dishes.
Unlike guajillos, puya chilies tend to retain their puffy round cross-section when dried.
SHU: 5,000-8,000 (moderately high)
Chipotle meco chilies (or chipotle peppers) are specific chipotle variety, made from dried and long-smoked ripe jalapeño peppers. Chipotle mecos tend to be much more smoky tasting than their cousin the morita pepper. The flavourful, smoky-sweet nature of chipotles make them one of the most popular and distinctive of all of the Mexican chilies.
Chipotles vary quite a bit in terms of heat, but are generally at least moderately spicy. Because of their popularity in Mexican and Tex-Mex cooking, they tend to be fairly easy to find.
SHU: 3,000-10,000 (moderately high)
Morita chipotle chilies (often simply called moritas) are specific chipotle variety, made from dried and gently-smoked ripe jalapeño peppers. Moritas tend to be much more fruitier tasting than their cousin the chipotle meco.
Morita peppers are often treated as a distinct pepper, separate from the more commonly used chipotle meco. They tend to work best in dishes that call for moderate smoke along with a bright fruity flavour. Availability is variable, but generally fairly good.
SHU: 3,000-10,000 (moderately high)
Árbol chilies (often called by their Spanish name, chiles de árbol) are perhaps the most popular of the hot chilies in Mexican cooking. They have a clean, sharp flavour with a healthy but not overwhelming level of heat. Most notably, they have a brilliant, bright red colour that makes sauces and salsa look absolutely gorgeous.
Because they’re arguably the most popular of the Mexican hot chilies, they tend to be fairly easy to find. They’re also quite easy to work with, and can be adjusted in terms of heat by leaving or removing the loose seeds inside the pepper.
SHU: 15,000-30,000 (high)
Chiles japones, often sold as Chinese or Tianjin Chilies (the Pantry Page deals with some of the confusion surrounding the name), are a small, spicy red chili with a clean taste and a distinctive bite. Because they’re popular in both Central American and East Asian cooking, they tend to be fairly easy to find.
These peppers pack a considerable punch, but their small size makes it easy to adjust the number you use. Seeded and membranes removed, they provide a healthy but manageable spice level that’s much appreciated in Asian cooking.
SHU: 40,000-75,000 (high)
