Add dried chiles to large heavy-bottomed Dutch oven or stock pot and cook over medium-high heat, stirring frequently, until slightly darkened with intense, roasted aroma, 2 to 5 minutes. Do not allow to smoke. Remove chiles to small bowl and set aside. Alternatively, place dried chilies on a microwave-safe plate and microwave on high power in 15-second increments until pliable and toasted-smelling, about 30 seconds total. Transfer to a 2-quart microwave-safe liquid measuring cup or bowl. Add water and chipotle chilies, cover with plastic wrap, and microwave on high power until gently simmering, about 5 minutes. Remove from microwave and set aside. Transfer chilies and liquid to blender and blend, starting on the lowest possible setting and gradually increasing speed to high (make sure to hold the lid down with a clean kitchen towel or a potholder to prevent it from blowing out). Blend until smooth, about 1 minute.
