Preheat your oven to broil. Put the poblano chile peppers on a parchment-lined cookie sheet cook until the skins begin to blacken and blister, rotating the chile peppers until all sides are evenly black and the outer skin is blistering off the peppers. This took me about 20 minutes total.
Peel the skins off of each pepper under cold running water. Remove the stems and seeds and be careful not to touch your eyes!
Combine the chile peppers, broth, salt, pepper and nutmeg in a blender, blending until smooth.
In a saucepan over medium heat, warm up the milk and set it aside. In another saucepan over medium heat, melt your butter, add the flour and stir well. Add the milk and whisk until it's blended evenly. Add the chile pepper mixture and corn, whisking to combine everything, then reduce the heat to low and simmer for 30 minutes.
Pour into bowls and top with a drizzle of melted queso!
