The poblano is pronounced: poh blah noh. Poblano peppers are mild, heart-shaped peppers that are large and have very thick walls, which make them great for stuffing. Chile rellenos are often made with poblano peppers. Poblanos are usually roasted and peeled before use. Poblano chiles, when dried, are called ancho or mulato chiles.
The poblano rates between 1,000 and 2,000 Scoville units on the heat index.
