Poblano chiles are one of the most complexly flavored mild to medium heat chiles. The peppers are mild to hot chile with a Scoville scale at 1,000 to 2,000 heat units. At their peak ripeness, their elongated, heart-shaped, curved and contorted pod is glossy, deep green and thick. The chile contains a cotton-textured membrane laden with small white seeds. When cut, the chile's aromas reveal a preview of its flavors: spicy, earthy, rich and bright. Cooking the chile brings out more flavor profiles, offering depth and undertones both smoky and savory. Aged and dried forms of Poblanos become significantly warmer and develop more depth in flavor.
