Guajillo Chiles: Pepper Type, Scoville, Flavor, Uses

What are Guajillo Chiles?

Guajillo Chile (also called chile guajillo or guajillo pepper) is the dried form of mirasol chile, a variety of chile pepper of the species of Capsicum annuum. Mexican farmers from the state of Zacatecas are chief producers of this chile. After poblano (ancho), this is the most popularly used chile in Mexican cuisines.

Mirasol, which means “looking at the sun,” is in reference to how these chiles grow pointing to the sky.

Mirasol peppers are allowed to age on the vine from their tender green stage into their mature brown-red color. When mature, they are picked for drying into Guajillos.

There are three Mirasol chiles, chile guajillo, chile puya, and chile cascabel; all of them have similar features. Chile cascabel is the closest in flavor to Guajillo chiles though slightly fruitier. Chile puya is smaller but spicier. Chile Guajillo is the largest Mirasol chile and has the richest flavor.

Along with Ancho and Pasilla peppers, this hot chile is part of the “holy trinity” of Mexican chiles.

Most groceries with Mexican spices sell this chile in whole, dried, ground, or paste forms.

Guajillo Pepper Scoville

Guajillo peppers are medium-hot chiles that sit on the Scoville Scale between 2,500 to 5,000 SHU. In comparison to jalapenos (2,500 to 8,000 SHU), both of them are on equal footing but occasionally Jalapenos can be quite a bit hotter. This chile is 6 to 20 times milder than cayenne pepper (30,000 to 50,000 SHU).

While considering the dried chilies, Chipotle peppers share the near equal spiciness of Guajillos. Among the Holy Trinity of Mexican chilies, Guajillo is the hottest; Ancho pepper (dried poblano) ranges from 1,000 to 1,500 SHU and Pasilla chilies range from 1,000 to 2,500 SHU.

Almost everyone will enjoy a milder range of medium-hot peppers; its spiciness is tolerable for most of us.
