The poblano is a mild chili pepper originating in the state of Puebla, Mexico. Dried, it is called ancho or chile ancho, from the Spanish word ancho. Stuffed fresh and roasted it is popular in chiles rellenos poblanos.
Somewhat large and heart-shaped, the poblano is common in Mexican dishes such as chiles rellenos.
Are poblano peppers spicy?
Yes, but only mildly spicy.
At maturity, the poblano turns dark red-brown and can be dried, at which point it's referred to as an ancho or mulato.
Which is hotter poblano or jalapeno?
There's quite a difference in spiciness between these two peppers. Whereas poblanos max out at 2,000 Scoville Heat Units (Pepperscale says on average, poblanos will have around 1,250 SHUs), jalapeños range between 2,500 to 8,000 SHUs.
That means a jalapeño could be up to eight times hotter than a poblano pepper.
