Spicy Poblano and Corn Soup

Poblano chile peppers are in peak season in summer and early fall. Ripe specimens are reddish brown and sweeter than the green ones. Be sure to remove the seeds and membranes before cooking; that's where the heat comes from.

Pantry Checklist:

• 1 package frozen baby gold and white corn
